text: England at the FIFA World Cup

text: History[edit]

text: Brazil 1950[edit]

text: England's first qualifying campaign for the FIFA World Cup doubled as the 1950 British Home Championship. The series kicked off for England on 15 October 1949 at Ninian Park, Cardiff, against Wales. Stan Mortensen gave England the lead after twenty two minutes, and just seven minutes later, Jackie Milburn doubled the lead. This was the first goal of Milburn's hat trick, which left England 4–0 up with 20 minutes to play. Mal Griffiths scored a consolation goal for Wales ten minutes from time, but England held on for a comfortable victory.

text: A month later, England welcomed Ireland to Maine Road, and it began well for the home side as Jack Rowley scored inside six minutes. England were already 6–0 up, thanks to Jack Froggatt, two for Stan Pearson, Stan Mortensen and a second from Rowley, by the time Ireland struck back through Samuel Smyth after 55 minutes. Rowley added a third and a fourth to his tally in the three minutes following Smyth's goal, however, leaving the score at 8–1 at the hour mark. The frantic scoring rate calmed down after that, with only one apeice before the final whistle, with Stan Pearson completing his brace for England's ninth, and Bobby Brennan scoring for Ireland.

text: It was not until May 1950 that England travelled to Hampden Park to face Scotland, who were also undefeated after their games against Ireland and Wales. With the top two from the group qualifying, both teams were guaranteed progression to the finals, and the game was solely for the honour of winning the British Home Championship, and the seeding advantage to be enjoyed upon reaching Brazil. A solitary goal from Roy Bentley gave England the victory, the title and the top spot in the group.

text: 1950 Finals[edit]

text: England were seeded in pot one for the finals, which meant they were the favourites to progress from Group 2, which also contained Spain, Chile and the United States. England's campaign kicked off against Chile in Rio de Janeiro, and, as was expected, England cruised to a 2–0 victory, courtesy of goals from Stan Mortensen and Wilf Mannion.[citation needed]

text: Their troubles began four days later when they faced the Americans in Belo Horizonte in what has become one of the most famous matches of all time. Joe Gaetjens scored the only goal of the match to give the United States an unlikely victory, which has gone down as one of the World Cup's greatest upsets. A myth arose that the English newspapers were so confident of an English victory that when the result was telegrammed back, they assumed a misprint and printed the score as 10–1 in England's favour. However, this has proven to be untrue.[5]

text: This left England in a sticky situation prior to their final match, against Spain in Rio. They needed to win, and for Chile to beat the United States to stand any chance of going through, and even then they would need the goal averages to fall in their favour. As it turned out, no such calculations were necessary, despite Chile's victory, as Spain's Zarra scored the only goal of the game, eliminating England from the competition.

text: As with their first World Cup, England's qualifying for the 1954 edition also constituted the 1953–54 British Home Championship. They played Wales at Ninian Park as their first match once again, and the 4–1 result was the same. However, unlike four years earlier, it was the home side that went into the lead, after twenty two minutes through Ivor Allchurch. Despite being 1–0 down at half time, England scored four within eight minutes of the restart; two each for Dennis Wilshaw and Nat Lofthouse.

text: Goodison Park was the venue for England's home clash against Ireland, who were newly renamed Northern Ireland. Harold Hassall got England off to a good start with a goal after just ten minutes. Eddie McMorran put the Irish back on terms just before the hour mark, but Hassall completed his brace six minutes later. Lofthouse completed a comfortable 3–1 win for England.

text: With the top two in the group qualifying for the finals, the final game between England and Scotland, at Hampden Park, settled nothing except the placings within the group, despite Scotland having dropped a point with a 3–3 draw at home to Wales. Allan Brown put the home side ahead after just seven minutes, but it was all square again thanks to Ivor Broadis just four minutes later. Johnny Nicholls gave England the lead for the first time just after half time, and they began to extend a lead after Ronnie Allen's 68th-minute goal. Jimmy Mullen made the game all but certain seven minutes from time, and although Willie Ormond scored a consolation for Scotland with just 1 minute to play, England topped the competition for the second time in a row.

text: 1954 Finals[edit]

text: England were drawn in Group 4 for the finals, with hosts Switzerland, Italy and Belgium. In an odd twist, unique to the 1954 tournament, England and Italy, as the two seeded teams in the group, did not have to play each other.

text: Equally, Switzerland and Belgium did not have to play each other. England's first game in Switzerland was against Belgium in Basel, and they suffered a shock as Léopold Anoul put the Belgians into the lead after just five minutes. Ivor Broadis put the favourites back on terms just over twenty minutes later, and although Nat Lofthouse gave England the lead 10 minutes later, it was proving to be tougher than they had expected against the Belgians.

text: Broadis scored his second just after the hour, but Henri Coppens hit back four minutes later to keep Belgium in the game at only 3–2 down. Anoul completed his brace another four minutes after that to level the scores again. In another oddity peculiar to this World Cup, drawn matches in the group stage would go to extra time, and as such the teams played on with the score at 3–3.

text: Just one minute into the added period, Lofthouse added a fourth for England and they seemed to have won it, but Jimmy Dickinson scored an own goal three minutes later to put the score back at 4–4. It stayed this way until the extra period was up, and as penalty shoot-outs were yet to be invented and replays were not used in the group, the match was recorded as a draw.

text: England's second and final group game was against the hosts in Bern. This proved to be an easier game for the Three Lions, and they scored one goal in each half (from Jimmy Mullen and Dennis Wilshaw respectively) to give them a comfortable win of 2–0. As Switzerland (against England), Italy (against Switzerland) and Belgium (against Italy) had all lost one game, England progressed as group winners, along with Switzerland, who won a play-off against Italy.

text: England faced the winners of group three and defending champions Uruguay in the quarter-finals. Carlos Borges gave the South Americans the lead inside 5 minutes, but Lofthouse put England back on terms ten minutes later. England were clearly struggling, but held on until just before half time, when Obdulio Varela gave the lead back Uruguay.

text: Juan Alberto Schiaffino doubled the lead just after the break, but Tom Finney kept England's foot in the door with his sixty seventh-minute goal. However, it was all over after Javier Ambrois restored the two goal lead with twelve minutes to play. The score remained at 4–2, and England were eliminated from the cup.

text: Sweden 1958[edit]

text: For the first time, England had to play against countries other than the Home Nations to reach the Finals in Sweden. They were drawn against the Republic of Ireland and Denmark. In the qualifying round, England won three out of the four games and drew the other. Four months before the World Cup, Roger Byrne, Duncan Edwards, David Pegg and Tommy Taylor all lost their lives in the Munich air disaster while playing for Manchester United. At the finals, which is the only tournament to have seen all Home Nations take part, the Home Nations were all drawn in different groups.

text: England were drawn against the Soviet Union (2–2), Brazil (0–0) and Austria (2–2), who finished third in the 1954 World Cup. At the end of the group stage, Soviet Union and England each had three points, and had scored four goals and conceded four goals. This meant there was a play-off to decide the second-placed team in the group, the winner to qualify. England lost the play-off 1–0 and were thus knocked out. The only consolation for England was that they were the only team to play the eventual winners Brazil and not lose.

text: Chile 1962[edit]

text: The third World Cup which took place in South America, saw England qualify by successfully qualifying from the group, which contained Portugal and Luxembourg, defeating Luxembourg on both occasions, and defeating Portugal at home, and drawing in Lisbon.

text: At the finals, England were drawn in a group with Hungary, Argentina and Bulgaria. England defeated Argentina 3-1, thanks to goals from Ron Flowers, Bobby Charlton and Jimmy Greaves,[6] before playing out a goalless draw with Bulgaria, and a 2–1 defeat to Hungary.[7]

text: England finished in second place behind Hungary and played the winners of group 3, defending champions Brazil, in the quarter-finals. Brazil scored first through Garrincha, before an equaliser for Gerry Hitchens before half time. However, second-half goals from Garrincha and Vavá meant Brazil won the game 3–1, and eliminated England from the competition.[8] This defeat was manager Walter Winterbottom's last game in charge. Winterbottom had led England to four World Cup Finals. From May 1963, Alf Ramsey became the manager of England.

text: England 1966[edit]

text: This section needs expansion. You can help by adding to it. (July 2018)

text: In the 1966 World Cup Finals, England used their home advantage and, under Ramsey, won their first, and only, World Cup title. England played all their games at Wembley Stadium in London, which became the last time that the hosts were granted this privilege. After drawing 0–0 in the opening game against former champions Uruguay, which started a run of four games all ending goalless. England then beat both France and Mexico 2–0 and qualified for the quarter-finals.[citation needed]

text: The quarter-finals saw England play Argentina, which ended in a 1–0 win to England. This match saw the start of the rivalry between England and Argentina, when Argentinian Antonio Rattín was dismissed by German referee Rudolf Kreitlein in a very fierce game. A 2–1 win against Portugal in the semi-final then followed. Portugal were the first team to score against England in the tournament. The final saw England play West Germany, with the result finishing in a 4–2 win for England, after extra time.[citation needed]

text: Mexico 1970[edit]

text: 1970 saw the first World Cup finals take place in North America and England qualified automatically for the tournament by winning the 1966 FIFA World Cup. England were drawn in a group with Romania, former world champions Brazil and Czechoslovakia. Each of the matches only saw one goal, with England defeating Romania and Czechoslovakia, and losing to Brazil. The quarter-final saw a repeat of the 1966 final, with England playing West Germany. England were hampered by the fact that first-choice goalkeeper Gordon Banks was ill, and Peter Bonetti played instead. England led 2–0 with goals by Alan Mullery and Martin Peters, but in the 70th minute, Franz Beckenbauer pulled one goal back for West Germany.

text: After Beckenbauer's goal, Ramsey substituted Bobby Charlton, who overtook Billy Wright as England's most capped player ever, with caps totalling 106. Uwe Seeler equalised for the Germans in the eighty first minute, thereby taking the game into extra time. During extra time, Gerd Müller scored the winning goal for West Germany which saw the German side win 3–2. This turned out to be Charlton's last game for England.[9]

text: West Germany 1974[edit]

text: For the first time, England did not qualify for a World Cup. In a group with Olympic champions Poland and Wales, England could not overtake Poland. After only drawing at home to Wales 1–1 and losing the first leg 2–0 to Poland, meant that England had to beat Poland at home, whilst Poland only needed to draw. Poland managed to withstand England's attacks in the first half, who had Martin Peters playing for them. Poland took the lead in the 57th minute with a goal from Jan Domarski.

text: England equalised six minutes later, with a penalty converted by Allan Clarke. England were unable to score any more goals with goalkeeper Jan Tomaszewski keeping England at bay. Brian Clough had previously called Tomaszewski a "clown".[10] The commentator of the game then said "it's all over".[11] Poland took this good form to the finals and ended in third place. After failing to qualify, Alf Ramsey resigned from his post and after a time, where Ramsey and his predecessor had lasted a total of 29 years, no manager was able to last in the job for longer than eight years. This ended when Bobby Robson became England manager.[12]

text: Argentina 1978[edit]

text: England also did not qualify for the fourth World Cup which took place in South America. This time, England were denied by Italy, who had scored three more goals than England after both teams finished on the same points. Goals scored dictated who qualified after the head-to-head record between the two sides finished the same, following a 2–0 home win for each team. The lower-ranked teams in the group were Finland and Luxembourg, but the size of the wins against them proved to be decisive. Nevertheless, Ron Greenwood was given a second chance in charge of England, after taking the role in 1977.

text: Spain 1982[edit]

text: 1982 saw the first time where the European Qualifying Rounds were divided into groups of five teams, where the top two teams qualify for the World Cup. Greenwood used his second chance and took England to Spain by finishing second behind Hungary and above Romania, Switzerland and Norway.

text: At the finals, England won all three group games, defeating France 3-1, with a brace from Bryan Robson,[13] before beating Czechoslovakia 2–0, with a Jozef Barmos own goal, [14] and World Cup newcomers Kuwait 1–0, thanks to a Trevor Francis goal.[15]

text: The next round saw a second group stage consisting of three teams, a first time event at the World Cup. England drew with West Germany 0–0 and after the Germans beat Spain 2–1, England then had to beat Spain with a two-goal difference to progress to the next round. England, however, only managed a 0–0 draw against the Spanish. England remained unbeaten at the end of the tournament. After the World Cup, Ron Greenwood's time as England manager ended, and he was replaced by Bobby Robson.

text: Mexico 1986[edit]

text: 1986 saw the second World Cup to take place in Mexico. England qualified for Mexico 1986 by winning four games and drawing four times against Northern Ireland, who qualified in second place, Romania, Finland and Turkey. In Mexico, England lost their opening game to Portugal 1–0 and could only manage a goalless draw against Morocco. The final group game, however, saw England beat Poland 3–0, which is one of the three highest scores for England at the World Cup, with Gary Lineker scoring a hat-trick.

text: This result took England to second place and finished behind Morocco. England then also beat Paraguay 3–0 in the Round of 16. In the quarter-finals, England renewed their rivalry with Argentina in a game that has become notorious for the Argentina goals, both scored by Diego Maradona. Maradona's first goal, known as the Hand of God, was illegal and should not have counted, as he used his hand to punch the ball into the net. However, the referee missed this infringement, and ruled that the goal should stand. Maradona then made the score 2-0, famously dribbling from inside Argentina's half and around several English players before scoring. Gary Lineker pulled back the score to 2-1, but England ran out of time to equalise, and were eliminated. Nevertheless, Lineker finished with the Golden Boot by scoring six goals and thereby becoming England's first Golden Boot winner.

text: Italy 1990[edit]

text: By winning three and drawing three, England qualified for Italia '90, the second World Cup to be held in Italy, scoring ten goals and conceding none. England were unbeaten through qualification, winning three games, and drawing the remaining three, but still finished second to Sweden, whom they drew with twice.[16] England profited from Romania's 3–1 win over Denmark, who, had they won, would have qualified as the third-best second-placed team. West Germany and England were able to qualify for Italia '90 as the best second-placed teams in the groups with four teams.

text: Because a few years previously saw English hooligans at European competition matches, England were forced to play their group games on Sardinia and Sicily. In group F, was the European champions Netherlands, the Republic of Ireland and Egypt and England. After opening the tournament with a 1–1 draw against Ireland and a 0–0 draw against the Dutch, England then beat Egypt 1–0. This was Egypt's first appearance since the 1934 World Cup.[citation needed] England won the group with four points.[17]

text: In the next round, England had to play Belgium. The game went to extra time, and in the hundredth and nineteenth minute, David Platt scored the winning goal.[18] England also had to play extra time against Cameroon in the quarter-finals. Cameroon were the first African team to have reached the quarter-finals. England opened the scoring through David Platt, but Cameroon quickly turned around the game to lead 2-1. Lineker subsequently won and scored a penalty in the 83rd minute to ensure the game went to extra time. He then scored a second penalty, to see England reach the semi-finals.[19]

text: In the semi-finals, England met West Germany. There was no separating the two teams after 90 minutes, which made England the first team to have played extra time in three successive World Cup games. There was also no separating the two teams after extra time, thereby taking the game to penalties.[20]

text: Although English goalkeeper Peter Shilton dived the right way for every penalty, he was unable to save any. German goalkeeper Bodo Illgner, having failed to save any of England's first three penalties, saved England's fourth penalty, taken by Stuart Pearce. Olaf Thon then scored for Germany, meaning that England's Chris Waddle would have to score his fifth penalty and hope that Shilton saved the Germans' fifth penalty. However, Waddle's penalty missed completely, going high over the crossbar, thereby resulting in England's being knocked out of the competition.[20] The third-place playoff between England and Italy saw England lose their only game of the tournament in normal time. Even though this was England's best finish since the 1966 World Cup, Bobby Robson's time as England manager had come to an end.[21][22]

text: United States 1994[edit]

text: For the 1994 World Cup in the United States, under the leadership of new manager Graham Taylor, England surprisingly did not qualify for the tournament. In a group with six teams, England lost to Norway and the Netherlands, finishing third above Poland, Turkey and San Marino.

text: England went into their final game with San Marino knowing they would need a seven-goal victory and for Poland to beat the Netherlands in the other match in order to qualify.[23] In the game against San Marino, Davide Gualtieri scored against England after nine seconds, taking the lead for the outsiders. England went on to win 7–1, which was too small a goal margin. Additionally, despite the half-time score between the Poles and the Dutch being 1-1, the Dutch went on to win 3-1, meaning that however many goals England scored, they could still not qualify. Taylor's tenure in charge ended and he was replaced by Terry Venables, who was dismissed after England lost the semi-final of Euro 1996, hosted in England.[12]

text: France 1998[edit]

text: After missing out on the World Cup in 1994, England, managed by Glenn Hoddle, qualified for the World Cup in France. England were drawn in Group 2 of UEFA qualifying with Italy, Poland, Georgia and Moldova. England beat Poland, Georgia and Moldova both home and away, but a home defeat to Italy in their fourth match meant they went into the final qualifier at the Stadio Olimpico in Rome just a point ahead of the Azzurri and only needing a draw to qualify automatically; defeat would see them have to navigate a play-off to secure qualification. The match finished as a goalless draw and England finished top of the group.

text: At the finals in France, England played in Group G. England defeated Tunisia 2–0 in the first game, with goals from Alan Shearer and Paul Scholes.[24] Their second match saw England lose 2–1 to Romania; despite an 81st-minute equaliser from Michael Owen, Dan Petrescu scored a winner shortly before injury time. In their final group game, England defeated Colombia 2–0 in the decisive match, thanks to goals from midfielders Darren Anderton and David Beckham.[25] England finished second in Group G, which saw them qualify for the last 16 phase, and play the winner of 1998 FIFA World Cup Group H, Argentina.

text: In a fiery game containing six yellow cards and two penalties, David Beckham was controversially sent off in the 47th minute for what many felt was at most a yellow card offence, knocking over Diego Simeone.[26][27] Gabriel Batistuta opened the scoring from the penalty spot in the fifth minute of the game, before an equaliser also from the spot by Alan Shearer four minutes later. England took the lead through Owen, in the 16th minute. Argentina drew level through Javier Zanetti in injury time of the first half.

text: The game finished 2-2, and, as neither team were able to find a winner in extra time, penalties were needed to decide the team that qualified to the next round. While David Seaman did save one penalty, Argentine goalkeeper Carlos Roa managed to save two, including the vital one from David Batty, thereby knocking England out of the World Cup. Beckham subsequently received death threats and was sent bullets in the post.[28][29]

text: South Korea/Japan 2002[edit]

text: In 2002 the World Cup took place in Asia for the first time. England, under its first ever foreign manager in Swedish Sven-Göran Eriksson, were able to qualify for the tournament. England were drawn in Group 9, alongside Germany, Finland, Greece and Albania. In the last ever game in the original Wembley Stadium, (which closed after the match) England played Germany, losing 1–0, the only goal scored by Dietmar Hamann. The match was the last under the management of Kevin Keegan, who resigned at the end of the match, and was replaced by Eriksson.[30] By beating Germany 5–1 in Munich, England's qualifying campaign was revitalised, and they qualified automatically, by drawing 2–2 with Greece. Germany, who could only draw 0–0 with Finland, had to play a play-off game against Ukraine, with England qualifying ahead winning the group.

text: In Japan, England had to play against Eriksson's homeland, Sweden, and both settled out for a 1–1 draw. England and Beckham gained a measure of revenge for their previous 1998 defeat in defeating Argentina 1-0, thanks to a Beckham penalty. However, England could only manage a disappointing 0-0 draw against Nigeria, meaning that although they were able to qualify for the second round, where they played Denmark, they qualified as runners up, which meant that they would meet favourites Brazil in the quarter-finals if they qualified.

text: England played Denmark in the round of 16 defeating Denmark 3–0, thanks to goals from Micheal Owen, Rio Ferdinand, and Emile Heskey.[31] England played four-time World Cup winners and 1998 runners-up Brazil in the quarter-finals. Despite leading through a Michael Owen goal, a mistake by David Seaman saw England lose 2–1, and Brazil won their fourth World Cup match against England, and went on to win the tournament.[32]

text: Germany 2006[edit]

text: England were drawn into Group 6 of European qualifying for the 2006 World Cup. The group featured other home nations in Wales, and Northern Ireland, as well as Poland (who had eliminated England the last time the World Cup took place in Germany), Azerbaijan and Austria. England won eight of the 10 games, and qualified as group winners, in front of Portugal, despite drawing to Austria in Vienna, and losing to Northern Ireland in Belfast.[33]

text: In Germany, however, England were less convincing. England played in Group B, alongside Paraguay, Trinidad and Tobago, and Sweden. England started with a 1–0 win against Paraguay; which was won due to a 3rd minute own goal.[34] The second game against first time qualifiers Trinidad and Tobago saw England have to wait until the 83rd minute for England to take the lead, with Peter Crouch opened the scoring with a goal many felt was illegal, and the second goal of the game coming in added time from Steven Gerrard.[35][36] The last group game saw England play against Sweden, where an eventual 2-2 draw saw them qualify for the next round as group winners, thereby avoiding playing hosts Germany.[37]

text: In the last 16 stage, a free kick from David Beckham saw England win 1–0 against Ecuador and reach the quarter-finals, where they faced Portugal.[38] The game finished goalless, and England once again were knocked out on penalties and Portuguese goalkeeper Ricardo became the first goalkeeper to save three penalties in a penalty shoot-out. Ricardo saved from Frank Lampard, Steven Gerrard, and Jamie Carragher; the only England player who successfully converted his penalty was Owen Hargreaves. Portugal won the shoot-out 3-1, despite misses from Petit and Hugo Viana. This game was also Erickson's final match as England manager.[39]

text: South Africa 2010[edit]

text: Qualification for the first African World Cup went successfully for new England manager Fabio Capello, after previous manager Steve McClaren was unable to secure qualification to the Euro 2008. By winning nine times and only losing to Ukraine, England qualified ahead of Croatia, Belarus, Kazakhstan and Andorra. England's group was seen as a favourable one, containing comparatively much weaker teams.[40] However, England opened up their campaign with a 1–1 draw against the United States, thanks to a major error by goalkeeper Robert Green. They then drew 0–0 against Algeria and were booed off the field by their own fans, drawing the ire of striker Wayne Rooney.[41] England eventually qualified for the next round by beating Slovenia 1–0, but only qualified as runners up to the United States, thereby meaning they would draw favourites Germany.

text: In the second round match, Germany took the lead after 20 minutes after goalkeeper Manuel Neuer played the ball down the pitch to Miroslav Klose, who opened the scoring. The score became 2–0 to Germany after 32 minutes. Shortly after, England defender Matthew Upson scored a header. Later, Frank Lampard had a shot at goal which was disallowed despite crossing the line; which was confirmed on replays. German goalkeeper Manuel Neuer admitted subsequently he knew the ball had crossed the line, but decided to deceive the referee.[42] The German media reported it was "revenge for Wembley", while the English media criticised FIFA's refusal to implement goal-line technology. Ironically, despite his earlier opposition to goal-line technology, Sepp Blatter said that it should be introduced after a Ukrainian goal against England at Euro 2012 was ruled out.[43][42][44] As England tried to equalise, Germany used this to their advantage and scored two more goals. This became Germany's biggest win against England in a World Cup, winning 4-1.[45]

text: Brazil 2014[edit]

text: Under Roy Hodgson, who replaced Fabio Capello after Euro 2012 after a disagreement between Capello and The FA, England qualified for the second World Cup to be held in Brazil. Ukraine were again one of the opponents in the qualifying rounds. The other opponents included Montenegro, Poland, Moldova and San Marino. After winning six games and drawing four, England qualified unbeaten.[46]

text: The draw for the finals saw England have to play against Italy and Uruguay, both former world champions, which meant that it was the first ever time three World Champions were drawn in the same group, along with Costa Rica. England lost to Italy and Uruguay, and were thus knocked out after two games. The final match against Costa Rica finished as a goalless draw. This performance was statistically their worst ever performance at a World Cup, ending up with just one point after two losses to Uruguay and Italy and a goalless draw with Costa Rica in the dead rubber match, their lowest points total in the group stage of a world cup.[46]

text: Russia 2018[edit]

text: England played in UEFA Group F in qualification for the 2018 World Cup, in a group of six with Slovakia, Slovenia, Scotland, Lithuania and Malta, with only the winner of the group guaranteed qualification. England went into the qualification process under manager Sam Allardyce, only for Allardyce to leave the post after just one game due to controversy regarding discussing breaking FIFA rules.[47]

text: Under Allardyce's replacement, Gareth Southgate, England went undefeated throughout qualification, winning eight matches out of 10, drawing with Slovenia 0–0 in Ljubljana, and drawing 2–2 with Scotland in Glasgow thanks to a 90th-minute equaliser from Harry Kane.[48] This was the third successive major tournament that England were undefeated, having been undefeated in 2014 World Cup, and Euro 2016 qualifying.

text: 2018 Finals[edit]

text: Under Gareth Southgate, the England team began their tournament in group G against Tunisia. The game started well for England with a goal from Harry Kane in the 11th minute. Tunisia equalised through Sassi from the penalty spot in the 35th minute following a foul by Kyle Walker. Some controversy followed as various potential offences against Harry Kane, inside the penalty area were ignored by the referee and no VAR checks were carried out. England persevered and scored a second goal in the 91st minute, again by Harry Kane, resulting in a 2–1 victory.[49]

text: In the second group stage match, England surpassed their record for goals scored in a World Cup match by beating Panama 6-1. Jesse Lingard scored the third goal, John Stones scored the first and fourth goals and Harry Kane scored a hat-trick with the second, fifth and sixth goals.[50]

text: In the final group stage match, England narrowly lost 1-0 to Belgium. Adnan Januzaj scored the sole goal of the game; but with both teams having fielded reserve teams, with England specificially making 9 changes. Before the game media outlets stating that a loss could potentially become beneficial, as the winner would be in the half of the draw with four of the top seven sides in the world.[c][51][52] The result that meant Belgium topped the group and England finished second, setting up a last 16 clash with Group H winners Colombia.[53][54]

text: England played their last 16 match in the Otkritie Arena, Moscow, with the same team as against Tunisia. Harry Kane scored his sixth goal of the tournament, and the third penalty, after once again being fouled in the box from a corner, similarly as against Panama.[55] The score remained at 1-0, until stoppage time, where a header from Yerry Mina beat Jordan Pickford in goal to bring the game to extra time. Neither team managed to score in extra time, and the match went to penalties, which England won 4-3.[56] As well as being the first knockout match England had won at a major tournament since 2006 (last defeating Ecuador in the last 16); it was the first time England won a World Cup penalty shoot-out.[d][58] The match was notable for the heated atmosphere the game was played in, with a total of eight yellow cards being shown in the match.[e][59]

text: England played against Sweden in their quarter-final at Cosmos Arena, Samara on 7 July 2018.[57] They won the match 2–0, with defender Harry Maguire scoring his first England goal, a header scored from a corner, and Dele Alli a second header from close range. This would send them through to their third World Cup semi-final and their first since 1990, and third overall.[60] The team played Croatia in the semi-final, resulting in a 2–1 loss after extra time.[61] England would later finish fourth in the competition, the best result since 1990. England would lose again to Belgium in the 3rd place playoff, thanks to goals from Thomas Meunier and Eden Hazard, despite a Eric Dier shot being cleared off the line by Toby Alderweireld.[62]

text: The tournament would see England score nine goals from set-pieces – the most by a team in a single World Cup tournament since 1966.[63]

text: Refereeing[edit]

text: Four FIFA World Cup finals were officiated by English referees, more than by any other football association. The first Englishman to officiate a final, George Reader, is also the oldest World Cup referee to date, as he was 53 years and 236 days old at the 1950 decisive match between Uruguay and Brazil. The other final referees are William Ling (1954), Jack Taylor (1974) and Howard Webb (2010).

text: Arthur Ellis, who was a linesman at the 1950 final, is part of an elite group of referees who has been called up for three consecutive World Cups (1950–1958).

text: Voyager 2

text: History[edit]

text: Background[edit]

text: In the early space age, it was realized that a coincidental alignment of the outer planets would occur in the late 1970s and enable a single probe to visit Jupiter, Saturn, Uranus, and Neptune by taking advantage of the then-new technique of gravity assists. NASA began work on a Grand Tour, which evolved into a massive project involving two groups of two probes each, with one group visiting Jupiter, Saturn, and Pluto and the other Jupiter, Uranus, and Neptune. The spacecraft would be designed with redundant systems to ensure survival through the entire tour. By 1972 the mission was scaled back and replaced with two Mariner-derived spacecraft, the Mariner Jupiter-Saturn probes. To keep apparent lifetime program costs low, the mission would include only flybys of Jupiter and Saturn, but keep the Grand Tour option open.[4]:263 As the program progressed, the name was changed to Voyager.[10]

text: The primary mission of Voyager 1 was to explore Jupiter, Saturn, and Saturn's moon, Titan. Voyager 2 was also to explore Jupiter and Saturn, but on a trajectory that would have option of continuing on to Uranus and Neptune, or being redirected to Titan as a backup for Voyager 1. Upon successful completion of Voyager 1's objectives, Voyager 2 would get a mission extension to send the probe on towards Uranus and Neptune.[4]

text: Spacecraft design[edit]

text: Constructed by the Jet Propulsion Laboratory (JPL), Voyager 2 included 16 hydrazine thrusters, three-axis stabilization, gyroscopes and celestial referencing instruments (Sun sensor/Canopus Star Tracker) to maintain pointing of the high-gain antenna toward Earth. Collectively these instruments are part of the Attitude and Articulation Control Subsystem (AACS) along with redundant units of most instruments and 8 backup thrusters. The spacecraft also included 11 scientific instruments to study celestial objects as it traveled through space.[11]

text: Communications[edit]

text: Built with the intent for eventual interstellar travel, Voyager 2 included a large, 3.7 m (12 ft) parabolic, high-gain antenna (see diagram) to transceive data via the Deep Space Network on the Earth. Communications are conducted over the S-band (about 13 cm wavelength) and X-band (about 3.6 cm wavelength) providing data rates as high as 115.2 kilobits per second at the distance of Jupiter, and then ever-decreasing as the distance increased, because of the inverse-square law. When the spacecraft is unable to communicate with Earth, the Digital Tape Recorder (DTR) can record about 64 kilobytes of data for transmission at another time.[12]

text: Power[edit]

text: The spacecraft was equipped with 3 Multihundred-Watt radioisotope thermoelectric generators (MHW RTG). Each RTG includes 24 pressed plutonium oxide spheres, and provided enough heat to generate approximately 157 W of electrical power at launch. Collectively, the RTGs supplied the spacecraft with 470 watts at launch (halving every 87.7 years), and will allow operations to continue until at least 2020.[11][13][14]

text: Launch and trajectory[edit]

text: The Voyager 2 probe was launched on August 20, 1977, by NASA from Space Launch Complex 41 at Cape Canaveral, Florida, aboard a Titan IIIE/Centaur launch vehicle. Two weeks later, the twin Voyager 1 probe would be launched on September 5, 1977. However, Voyager 1 would reach both Jupiter and Saturn sooner, as Voyager 2 had been launched into a longer, more circular trajectory.

Voyager 2 launch on August 20, 1977 with a Titan IIIE/Centaur.

Animation of Voyager 2's trajectory from 20 August 1977 to 31 December 2018   Voyager 2  ·   Earth ·   Jupiter  ·   Saturn ·   Uranus  ·   Neptune  ·   Sun

Trajectory of Voyager 2 primary mission.

Plot of Voyager 2's heliocentric velocity against its distance from the Sun, illustrating the use of gravity assists to accelerate the spacecraft by Jupiter, Saturn and Uranus. To observe Triton, Voyager 2 passed over Neptune's north pole, resulting in an acceleration out of the plane of the ecliptic, and, as a result, a reduced velocity relative to the Sun.[21]

text: In April 1978, a complication arose when no commands were transmitted to Voyager 2 for a period of time, causing the spacecraft to switch from its primary radio receiver to its backup receiver.[22] Sometime afterwards, the primary receiver failed altogether. The backup receiver was functional, but a failed capacitor in the receiver meant that it could only receive transmissions that were sent at a precise frequency, and this frequency would be affected by the Earth's rotation (due to the Doppler effect) and the onboard receiver's temperature, among other things.[22][23][24] For each subsequent transmission to Voyager 2, it was necessary for engineers to calculate the specific frequency for the signal so that it could be received by the spacecraft.

text: Encounter with Jupiter[edit]

text: Voyager 2's closest approach to Jupiter occurred on July 9, 1979. It came within 570,000 km (350,000 mi) of the planet's cloud tops.[25] It discovered a few rings around Jupiter, as well as volcanic activity on the moon Io.

text: The Great Red Spot was revealed as a complex storm moving in a counterclockwise direction. An array of other smaller storms and eddies were found throughout the banded clouds.

text: Discovery of active volcanism on Io was easily the greatest unexpected discovery at Jupiter. It was the first time active volcanoes had been seen on another body in the Solar System. Together, the Voyagers observed the eruption of nine volcanoes on Io, and there is evidence that other eruptions occurred between the two Voyager fly-bys.

text: The moon Europa displayed a large number of intersecting linear features in the low-resolution photos from Voyager 1. At first, scientists believed the features might be deep cracks, caused by crustal rifting or tectonic processes. The closer high-resolution photos from Voyager 2, however, left scientists puzzled: The features were so lacking in topographic relief that as one scientist described them, they "might have been painted on with a felt marker." Europa is internally active due to tidal heating at a level about one-tenth that of Io. Europa is thought to have a thin crust (less than 30 km (19 mi) thick) of water ice, possibly floating on a 50-kilometer-deep (30 mile) ocean.

text: Two new, small satellites, Adrastea and Metis, were found orbiting just outside the ring. A third new satellite, Thebe, was discovered between the orbits of Amalthea and Io.

text: Encounter with Saturn[edit]

text: The closest approach to Saturn occurred on August 26, 1981.[26]

text: While passing behind Saturn (as viewed from Earth), Voyager 2 probed Saturn's upper atmosphere with its radio link to gather information on atmospheric temperature and density profiles. Voyager 2 found that at the uppermost pressure levels (seven kilopascals of pressure), Saturn's temperature was 70 kelvins (−203 °C), while at the deepest levels measured (120 kilopascals) the temperature increased to 143 K (−130 °C). The north pole was found to be 10 kelvins cooler, although this may be seasonal (see also Saturn Oppositions).

text: After the fly-by of Saturn, the camera platform of Voyager 2 locked up briefly, putting plans to officially extend the mission to Uranus and Neptune in jeopardy. The mission's engineers were able to fix the problem (caused by an overuse that temporarily depleted its lubricant), and the Voyager 2 probe was given the go-ahead to explore the Uranian system.

text: Encounter with Uranus[edit]

text: The closest approach to Uranus occurred on January 24, 1986, when Voyager 2 came within 81,500 kilometers (50,600 mi) of the planet's cloud tops. Voyager 2 also discovered the moons Cordelia, Ophelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Belinda, Perdita and Puck; studied the planet's unique atmosphere, caused by its axial tilt of 97.8°; and examined the Uranian ring system.

text: Uranus is the third largest (Neptune has a larger mass, but a smaller volume) planet in the Solar System. It orbits the Sun at a distance of about 2.8 billion kilometers (1.7 billion miles), and it completes one orbit every 84 Earth years. The length of a day on Uranus as measured by Voyager 2 is 17 hours, 14 minutes. Uranus is unique among the planets in that its axial tilt is about 90°, meaning that its axis is roughly parallel with, instead of roughly perpendicular to, the plane of the ecliptic. This extremely large tilt of its axis is thought to be the result of a collision between the accumulating planet Uranus with another planet-sized body early in the history of the Solar System. Given the unusual orientation of its axis, with the polar regions of Uranus exposed for periods of many years to either continuous sunlight or darkness, planetary scientists were not at all sure what to expect when observing Uranus.

text: Voyager 2 found that one of the most striking effects of the sideways orientation of Uranus is the effect on the tail of the planetary magnetic field. This is itself tilted about 60° from the Uranian axis of rotation. The planet's magneto tail was shown to be twisted by the rotation of Uranus into a long corkscrew shape following the planet. The presence of a significant magnetic field for Uranus was not at all known until Voyager 2's arrival.

text: The radiation belts of Uranus were found to be of an intensity similar to those of Saturn. The intensity of radiation within the Uranian belts is such that irradiation would "quickly" darken — within 100,000 years — any methane that is trapped in the icy surfaces of the inner moons and ring particles. This kind of darkening might have contributed to the darkened surfaces of the moons and the ring particles, which are almost uniformly dark gray in color.

text: A high layer of haze was detected around the sunlit pole of Uranus. This area was also found to radiate large amounts of ultraviolet light, a phenomenon that is called "dayglow." The average atmospheric temperature is about 60 K (−350°F/−213°C). Surprisingly, the illuminated and dark poles, and most of the planet, exhibit nearly the same temperatures at the cloud tops.

text: The Uranian moon Miranda, the innermost of the five large moons, was discovered to be one of the strangest bodies yet seen in the Solar System. Detailed images from Voyager 2's flyby of Miranda showed huge canyons made from geological faults as deep as 20 kilometers (12 mi), terraced layers, and a mixture of old and young surfaces. One hypothesis suggests that Miranda might consist of a reaggregation of material following an earlier event when Miranda was shattered into pieces by a violent impact.

text: All nine of the previously known Uranian rings were studied by the instruments of Voyager 2. These measurements showed that the Uranian rings are distinctly different from those at Jupiter and Saturn. The Uranian ring system might be relatively young, and it did not form at the same time that Uranus did. The particles that make up the rings might be the remnants of a moon that was broken up by either a high-velocity impact or torn up by tidal effects.

text: Encounter with Neptune[edit]

text: Following a mid-course correction in 1987, Voyager 2's closest approach to Neptune occurred on August 25, 1989.[27][28][29] Because this was the last planet of the Solar System that Voyager 2 could visit, the Chief Project Scientist, his staff members, and the flight controllers decided to also perform a close fly-by of Triton, the larger of Neptune's two originally known moons, so as to gather as much information on Neptune and Triton as possible, regardless of Voyager 2's departure angle from the planet. This was just like the case of Voyager 1's encounters with Saturn and its massive moon Titan.

text: Through repeated computerized test simulations of trajectories through the Neptunian system conducted in advance, flight controllers determined the best way to route Voyager 2 through the Neptune-Triton system. Since the plane of the orbit of Triton is tilted significantly with respect to the plane of the ecliptic, through mid-course corrections, Voyager 2 was directed into a path about three thousand miles above the north pole of Neptune.[30] At that time, Triton was behind and below (south of) Neptune (at an angle of about 25 degrees below the ecliptic), close to the apoapsis of its elliptical orbit. The gravitational pull of Neptune bent the trajectory of Voyager 2 down in the direction of Triton. In less than 24 hours, Voyager 2 traversed the distance between Neptune and Triton, and then observed Triton's northern hemisphere as it passed over its north pole.

text: The net and final effect on Voyager 2 was to bend its trajectory south below the plane of the ecliptic by about 30 degrees. Voyager 2 is on this path permanently, and hence, it is exploring space south of the plane of the ecliptic, measuring magnetic fields, charged particles, etc., there, and sending the measurements back to the Earth via telemetry.

text: While in the neighborhood of Neptune, Voyager 2 discovered the "Great Dark Spot", which has since disappeared, according to observations by the Hubble Space Telescope. Originally thought to be a large cloud itself, the "Great Dark Spot" was later hypothesized to be a hole in the visible cloud deck of Neptune.

text: With the decision of the International Astronomical Union to reclassify Pluto as a "dwarf planet" in 2006, the flyby of Neptune by Voyager 2 in 1989 became the point when every known planet in the Solar System had been visited at least once by a space probe.

text: Interstellar mission[edit]

text: Once its planetary mission was over, Voyager 2 was described as working on an interstellar mission, which NASA is using to find out what the Solar System is like beyond the heliosphere. Voyager 2 is currently transmitting scientific data at about 160 bits per second. Information about continuing telemetry exchanges with Voyager 2 is available from Voyager Weekly Reports.[31]

text: In 1992 Voyager 2 observed the nova V1974 Cygni in the far-ultraviolet.[32]

text: In July 2004 an attempt was made to observe the impacts fragments of the comet Comet Shoemaker–Levy 9 with Jupiter.[32] The craft’s position meant it had a direct line of sight to the impacts and observations were made in the ultraviolet and radio spectrum.[32]  Voyager 2 failed to detect anything with calculations showing that the fireballs were just below the craft’s limit of detection.[32]

text: On November 29, 2006, a telemetered command to Voyager 2 was incorrectly decoded by its on-board computer—in a random error—as a command to turn on the electrical heaters of the spacecraft's magnetometer. These heaters remained turned on until December 4, 2006, and during that time, there was a resulting high temperature above 130 °C (266 °F), significantly higher than the magnetometers were designed to endure, and a sensor rotated away from the correct orientation. As of this date it had not been possible to fully diagnose and correct for the damage caused to Voyager 2's magnetometer, although efforts to do so were proceeding.[33]

text: On August 30, 2007, Voyager 2 passed the termination shock and then entered into the heliosheath, approximately 1 billion miles (1.6 billion km) closer to the Sun than Voyager 1 did.[34] This is due to the interstellar magnetic field of deep space. The southern hemisphere of the Solar System's heliosphere is being pushed in.[35]

text: On April 22, 2010, Voyager 2 encountered scientific data format problems.[36] On May 17, 2010, JPL engineers revealed that a flipped bit in an on-board computer had caused the issue, and scheduled a bit reset for May 19.[37] On May 23, 2010, Voyager 2 resumed sending science data from deep space after engineers fixed the flipped bit.[38] Currently research is being made into marking the area of memory with the flipped bit off limits or disallowing its use. The Low-Energy Charged Particle Instrument is currently operational, and data from this instrument concerning charged particles is being transmitted to Earth. This data permits measurements of the heliosheath and termination shock. There has also been a modification to the on-board flight software to delay turning off the AP Branch 2 backup heater for one year. It was scheduled to go off February 2, 2011 (DOY 033, 2011–033).

text: On July 25, 2012, Voyager 2 was traveling at 15.447 km/s relative to the Sun at about 99.13 astronomical units (1.4830×1010 km) from the Sun,[6] at −55.29° declination and 19.888 h right ascension, and also at an ecliptic latitude of −34.0 degrees, placing it in the constellation Telescopium as observed from Earth.[39] This location places it deep in the scattered disc, and traveling outward at roughly 3.264 AU per year. It is more than twice as far from the Sun as Pluto, and far beyond the perihelion of 90377 Sedna, but not yet beyond the outer limits of the orbit of the dwarf planet Eris.

text: On September 9, 2012, Voyager 2 was 99.077 AU (1.48217×1010 km; 9.2098×109 mi) from the Earth and 99.504 AU (1.48856×1010 km; 9.2495×109 mi) from the Sun; and traveling at 15.436 km/s (34,530 mph) (relative to the Sun) and traveling outward at about 3.256 AU per year.[40] Sunlight takes 13.73 hours to get to Voyager 2. The brightness of the Sun from the spacecraft is magnitude -16.7.[40] Voyager 2 is heading in the direction of the constellation Telescopium.[40] (To compare, Proxima Centauri, the closest star to the Sun, is about 4.2 light-years (or 7016396434357355000♠2.65×105 AU) distant. Voyager 2's current relative velocity to the Sun is 15.436 km/s (55,570 km/h; 34,530 mph). This calculates as 3.254 AU per year, about 10% slower than Voyager 1. At this velocity, 81,438 years would pass before Voyager 2 reaches the nearest star, Proxima Centauri, were the spacecraft traveling in the direction of that star. (Voyager 2 will need about 19,390 years at its current velocity to travel a complete light year)

text: On November 7, 2012, Voyager 2 reached 100 AU from the sun, making it the third human-made object to reach 100 AU. Voyager 1 was 122 AU from the Sun, and Pioneer 10 is presumed to be at 107 AU. While Pioneer has ceased communications, both the Voyager spacecraft are performing well and are still communicating.

text: In 2013 Voyager 1 was escaping the solar system at a speed of about 3.6 AU per year, while Voyager 2 was only escaping at 3.3 AU per year.[41] (Each year Voyager 1 increases its lead over Voyager 2)

text: By July 10, 2018, Voyager 2 was at a distance of 118 AU (1.77×1010 km) from the Sun.[6] There is a variation in distance from Earth caused by the Earth's revolution around the Sun relative to Voyager 2.[6]

text: Future of the probe[edit]

text: It was originally thought that Voyager 2 would enter interstellar space in early 2016, with its plasma spectrometer providing the first direct measurements of the density and temperature of the interstellar plasma.[42]

text: However, the spacecraft may instead reach interstellar space sometime in either late 2019 or early 2020, when it will reach a similar distance from the Sun as Voyager 1 did when it crossed into interstellar space back in 2012.  Voyager 2 is not headed toward any particular star, although in roughly 40,000 years it should pass 1.7 light-years from the star Ross 248.[43] And if undisturbed for 296,000 years, Voyager 2 should pass by the star Sirius at a distance of 4.3 light-years. Voyager 2 is expected to keep transmitting weak radio messages until at least 2025, over 48 years after it was launched.[44]

text: Golden record[edit]

text: Each Voyager space probe carries a gold-plated audio-visual disc in the event that either spacecraft is ever found by intelligent life-forms from other planetary systems.[47] The discs carry photos of the Earth and its lifeforms, a range of scientific information, spoken greetings from the people (e.g. the Secretary-General of the United Nations and the President of the United States, and the children of the Planet Earth) and a medley, "Sounds of Earth", that includes the sounds of whales, a baby crying, waves breaking on a shore, and a collection of music, including works by Mozart, Blind Willie Johnson, Chuck Berry's "Johnny B. Goode", Valya Balkanska and other Eastern and Western classics and ethnic performers.[48] (see also Music in space)


document_title: Brown recluse spider

question_text: where does the brown recluse spider live in the united states

text: Brown recluse spider

text: Description[edit]

text: The violin pattern is not diagnostic, as other spiders can have similar markings (e.g. cellar spiders and pirate spiders). For definitive identification it is imperative to examine the eyes. While most spiders have eight eyes, recluse spiders have six eyes arranged in pairs (dyads) with one medial pair and two lateral pairs. Only a few other spiders have three pairs of eyes arranged in this way (e.g., scytodids). Recluses have no obvious coloration patterns on the abdomen or legs, and the legs lack spines.[2] The abdomen is covered with fine short hairs that, when viewed without magnification, give the appearance of soft fur. The leg joints may appear to be a slightly lighter color.

text: Life-cycle[edit]

text: Adult brown recluse spiders often live about one to two years. Each female produces several egg sacs over a period of two to three months, from May to July, with approximately fifty eggs in each sac. The eggs hatch in about one month. The spiderlings take about one year to grow to adulthood. The brown recluse spider is resilient and can tolerate up to six months of extreme drought and scarcity or absence of food. On one occasion, a brown recluse survived in controlled captivity for over five seasons without any food at all.[3]

text: Behavior[edit]

text: A brown recluse's stance on a flat surface is usually with all legs radially extended. When alarmed it may lower its body, withdraw the forward two legs straight rearward into a defensive position, withdraw the rearmost pair of legs into a position for lunging forward, and stand motionless with pedipalps raised. The pedipalps in mature specimens are dark and quite prominent and are normally held horizontally forward. When threatened it usually flees, seemingly to avoid a conflict, and if detained may further avoid contact with quick horizontal rotating movements or even resort to assuming a lifeless pose (playing dead). The spider does not usually jump unless touched brusquely, and even then its avoidance movement is more of a horizontal lunge rather than a vaulting of itself entirely off the surface. When running, the brown recluse does not leave a silk line behind, which would make it more easily tracked when it is being pursued. Movement at virtually any speed is an evenly paced gait with legs extended. When missing a leg or two it appears to favor this same gait, although (presumably when a leg has been injured) it may move and stand at rest with one leg slightly withdrawn. During travel it stops naturally and periodically when renewing its internal hydraulic blood pressure that, like most spiders, it requires to renew strength in its legs.

text: Habitat[edit]

text: Brown recluse spiders build asymmetrical (irregular) webs that frequently include a shelter consisting of disorderly thread. They frequently build their webs in woodpiles and sheds, closets, garages, plenum spaces, cellars, and other places that are dry and generally undisturbed. When dwelling in human residences they seem to favor cardboard, possibly because it mimics the rotting tree bark which they inhabit naturally. They have also been encountered in shoes, inside dressers, in bed sheets of infrequently used beds, in clothes stacked or piled or left lying on the floor, inside work gloves, behind baseboards and pictures, in toilets, and near sources of warmth when ambient temperatures are lower than usual. Human-recluse contact often occurs when such isolated spaces are disturbed and the spider feels threatened. Unlike most web weavers, they leave these lairs at night to hunt. Males move around more when hunting than the females, which tend to remain nearer to their webs. The spider will hunt for firebrats, crickets, cockroaches, and other soft-bodied insects.[citation needed]

text: Distribution[edit]

text: The range lies roughly south of a line from southeastern Nebraska through southern Iowa, Illinois, and Indiana to southwestern Ohio. In the southern states, it is native from central Texas to western Georgia and north to Kentucky.[4][5]

text: Despite rumors to the contrary, the brown recluse spider has not established itself in California or anywhere outside its native range.[6] This directly contradicts numerous sensationalized media reports of bites occurring where these spiders are absent (and no specimens were found), such as a 2014 report from Thailand, where a man was claimed to have died from a brown recluse bite.[7] Over the last century, occasional spiders have been intercepted in various locations where they have no known established populations; these spiders may be transported fairly easily, though the lack of established populations well outside the natural range also indicates that such movement has not led to colonization of new areas, after decades of opportunities.[8][9] Note that the occurrence of brown recluses in a single building (such as a warehouse) outside of the native range is not considered a successful colonization; such single-building populations can occur (e.g., in several such cases in Florida),[10] but do not spread, and can be easily eradicated.[11]

text: There are other species of the genus Loxosceles native to the southwestern part of the United States, including California, that may resemble the brown recluse, but these species have never been documented as medically significant. The number of "false positive" reports based on misidentifications is considerable; in a nationwide study where people submitted spiders that they thought were brown recluses, of 581 from California only 1 was a brown recluse—submitted by a family that moved from Missouri and brought it with them (compared to specimens submitted from Missouri, Kansas, and Oklahoma, where between 75% and 90% were recluses).[12] From this study, the most common spider submitted from California as a brown recluse was in the genus Titiotus, whose bite is deemed harmless. A similar study documented that various arachnids were routinely misidentified by physicians, pest control operators, and other non-expert authorities, who told their patients or clients that the spider they had was a brown recluse when in fact it was not.[13] Despite the absence of brown recluses from the Western U.S., physicians in the region commonly diagnose "brown recluse bites", leading to the popular misconception that the spiders inhabit those areas.[14]

text: Bite[edit]

text: The bite frequently is not felt initially and may not be immediately painful, but it can be serious. The brown recluse bears a potentially deadly hemotoxic venom. Most bites are minor with no necrosis. However, a small number of brown recluse bites do produce severe dermonecrotic lesions (i.e. necrosis); an even smaller number produce severe cutaneous (skin) or viscerocutaneous (systemic) symptoms. In one study of clinically diagnosed brown recluse bites, skin necrosis occurred 37% of the time, while systemic illness occurred 14% of the time.[15] In these cases, the bites produced a range of symptoms common to many members of the Loxosceles genus known as loxoscelism, which may be cutaneous and viscerocutaneous. In very rare cases, bites can even cause hemolysis—the bursting of red blood cells.[16]

text: As suggested by its specific epithet reclusa (recluse), the brown recluse spider is rarely aggressive, and bites from the species are uncommon. In 2001, more than 2,000 brown recluse spiders were removed from a heavily infested home in Kansas, yet the four residents who had lived there for years were never harmed by the spiders, despite many encounters with them.[17][18] The spider usually bites only when pressed against the skin, such as when tangled within clothes, towels, bedding, inside work gloves, etc. Many human victims report having been bitten after putting on clothes that had not been worn recently, or had been left for many days undisturbed on the floor. The fangs of the brown recluse are so tiny they are unable to penetrate most fabric.[19]

text: Around 49% of brown recluse bites do not result in necrosis or systemic effects. When both types of loxoscelism do result, systemic effects may occur before necrosis, as the venom spreads throughout the body in minutes. Children, the elderly, and the debilitatingly ill may be more susceptible to systemic loxoscelism. The systemic symptoms most commonly experienced include nausea, vomiting, fever, rashes, and muscle and joint pain. Rarely, such bites can result in hemolysis, thrombocytopenia, disseminated intravascular coagulation, organ damage, and even death.[20] Most fatalities are in children under the age of seven[21] or those with a weak immune system.

text: While the majority of brown recluse spider bites do not result in any symptoms, cutaneous symptoms occur more frequently than systemic symptoms. In such instances, the bite forms a necrotizing ulcer as the result of soft tissue destruction and may take months to heal, leaving deep scars. These bites usually become painful and itchy within 2 to 8 hours. Pain and other local effects worsen 12 to 36 hours after the bite, and the necrosis develops over the next few days.[22] Over time, the wound may grow to as large as 25 cm (10 inches). The damaged tissue becomes gangrenous and eventually sloughs away.

text: Misdiagnosis[edit]

text: There is now an ELISA-based test for brown recluse venom that can determine whether a wound is a brown recluse bite, although it is not commercially available and not in routine clinical use. Clinical diagnoses often use Occam's razor principle in diagnosing bites based on what spiders the patient likely encountered and previous similar diagnoses.[5][15][23]

text: A new mnemonic device, "NOT RECLUSE", has been suggested as a tool to help laymen and medical professionals more objectively screen and diagnose potential cases of loxoscelism.[24]

text: There are numerous documented infectious and noninfectious conditions that produce wounds that have been initially misdiagnosed as recluse bites by medical professionals, including:

text:
Pyoderma gangrenosum
Infection by Staphylococcus
Infection by Streptococcus
Herpes
Diabetic ulcers
Fungal infection
Chemical burns

Toxicodendron dermatitis
Squamous cell carcinoma
Localized vasculitis
Syphilis
Toxic epidermal necrolysis
Sporotrichosis
Lyme disease[25]

text: Many of these conditions are far more common and more likely to be the source of necrotic wounds, even in areas where brown recluse spiders actually occur.[5] The most important of these is methicillin-resistant Staphylococcus aureus (MRSA), a bacterium whose necrotic lesions are very similar to those induced by recluse bites, and which can be lethal if left untreated.[26] Misdiagnosis of MRSA as spider bites is extremely common (nearly 30% of patients with MRSA reported that they initially suspected a spider bite), and can have fatal consequences.[27]

text: Reported cases of brown recluse bites occur primarily in Arkansas, Colorado, Kansas, Missouri, Nebraska, Oklahoma, and Texas. There have been many reports of brown recluse bites in California—though a few related species may be found there, none of these are known to bite humans.[6] To date, the reports of bites from areas outside of the spider's native range have been either unverified, or, if verified, the spiders have been moved to those locations by travelers or commerce. Many arachnologists believe that a large number of bites attributed to the brown recluse in the West Coast are either from other spider species or not spider bites at all. For example, the venom of the hobo spider, a common European species established in the northwestern United States and southern British Columbia, has been reported to produce similar symptoms as the brown recluse bite when injected into laboratory rabbits. However, the toxicity of hobo spider venom has been called into question as actual bites have not been shown to cause necrosis, and no such occurrences have ever been reported where the spider is native.[28]

text: Numerous other spiders have been associated with necrotic bites in medical literature. Other recluse species, such as the desert recluse (found in the deserts of southwestern United States), are reported to have caused necrotic bite wounds, though only rarely.[29] The hobo spider and the yellow sac spider have also been reported to cause necrotic bites. However, the bites from these spiders are not known to produce the severe symptoms that can follow from a recluse spider bite, and the level of danger posed by these has been called into question.[30][31] So far, no known necrotoxins have been isolated from the venom of any of these spiders, and some arachnologists have disputed the accuracy of spider identifications carried out by bite victims, family members, medical responders, and other non-experts in arachnology. There have been several studies questioning the danger posed by some of these spiders. In these studies, scientists examined case studies of bites in which the spider in question was identified by an expert, and found that the incidence of necrotic injury diminished significantly when "questionable" identifications were excluded from the sample set.[32][33] (For a comparison of the toxicity of several kinds of spider bites, see the list of spiders having medically significant venom.)

text: Bite treatment[edit]

text: First aid involves the application of an ice pack to control inflammation and prompt medical care. If it can be easily captured, the spider should be brought with the patient in a clear, tightly closed container so it may be identified.

text: Routine treatment should include immobilization of the affected limb, application of ice, local wound care, and tetanus prophylaxis. Many other therapies have been used with varying degrees of success, including hyperbaric oxygen, dapsone, antihistamines (e.g., cyproheptadine), antibiotics, dextran, glucocorticoids, vasodilators, heparin, nitroglycerin, electric shock, curettage, surgical excision, and antivenom.[34][35] None of these treatments have been subjected to randomized controlled trials to conclusively show benefit. In almost all cases, bites are self-limited and typically heal without any medical intervention.[5]

text: Outpatient palliative care following discharge often consists of a weak or moderate strength opioid (e.g. codeine or tramadol, respectively) depending on pain scores, an anti-inflammatory agent (e.g. naproxen, cortisone), and an antispasmodic (e.g. cyclobenzaprine, diazepam), for a few days to a week. If the pain and/or spasms have not resolved by this time, a second medical evaluation is generally advised, and differential diagnoses may be considered. Occasionally, an antibiotic is prescribed as well.

text: Cases of brown recluse venom travelling along a limb through a vein or artery are rare, but the resulting tissue mortification can affect an area as large as several inches and in extreme cases require excising of the wound.

text: Specific treatments[edit]

text: In presumed cases of recluse bites, dapsone is often used for the treatment of necrosis, but controlled clinical trials have yet to demonstrate efficacy.[36] However, dapsone may be effective in treating many "spider bites" because many such cases are actually misdiagnosed microbial infections.[37] There have been conflicting reports about its efficacy in treating brown recluse bites, and some have suggested it should no longer be used routinely, if at all.[38]

text: Wound infection is rare. Antibiotics are not recommended unless there is a credible diagnosis of infection.[39]

text: Studies have shown that surgical intervention is ineffective and may worsen outcome. Excision may delay wound healing, cause abscesses, and lead to scarring.[40]

text: Purportedly application of nitroglycerin stopped necrosis.[41] However, one scientific animal study found no benefit in preventing necrosis, with the study's results showing it increased inflammation and caused symptoms of systemic envenoming. The authors concluded the results of the study did not support the use of topical nitroglycerin in brown recluse envenoming. [42]

text: Antivenom is available in South America for the venom of related species of recluse spiders. However, the bites, often being painless, usually do not present symptoms until 24 or more hours after the event, possibly limiting the effect of this intervention.[43]

text: Spider Population Control[edit]

text: Due to increased fear of these spiders prompted by greater public awareness of their presence in recent years, extermination of domestic brown recluses is performed frequently in the lower midwestern United States. Brown recluse spiders possess a variety of adaptive abilities, including the ability to maintain homeostasis for several seasons with no food or water.[44] Additionally, these spiders survive significantly longer in a relatively cool, thermally stable environment.[45]

text: The most important precaution is to remove and reduce trash and rubbish from your property, such as woodpiles, boxes, plywood, tires, and trash cans—especially if they are stored right next to the house. With attached garages, block off house access by sealing cracks around doors and access holes for electrical conduits or plumbing. In the Midwest, some brown recluse bites occur when a sleeping person rolls over during the night, and the trapped spider bites. In the bedroom, move the bed away from the wall, remove any skirts or ruffles and remove all items stored under it. This minimizes chances that any spider can crawl onto the bed. Do not leave clothes and shoes on the floor, or shake them before dressing if they are left out. Apparel and equipment that is only occasionally worn should be stored in tightly closed plastic bags, especially if stored in the garage or other dark storage areas. Typically, pesticide control of spiders is difficult. There are various insecticides available in retail outlets labeled for spider control. However, spiders' perched legs allow them to walk over most pesticides, making the use of chemicals to eradicate the spiders impractical and unnecessarily toxic.[44] A 2014 study indicates that fumigation may be more effective than previously believed.[46] Sticky traps placed along floor boards offer a non-insecticidal way to trap spiders as well as provide an idea of population levels in the structure.
