A phylogenetic study by Jost & Shaw in 2006 using sequences from 18S, 28S, and 16S rRNA supported the monophyly of Ensifera. Most ensiferan families were also found to be monophyletic, and the superfamily Gryllacridoidea was found to include Stenopelmatidae, Anostostomatidae, Gryllacrididae and Lezina. Schizodactylidae and Grylloidea were shown to be sister taxa, and Rhaphidophoridae and Tettigoniidae were found to be more closely related to Grylloidea than had previously been thought. The authors stated that "a high degree of conflict exists between the molecular and morphological data, possibly indicating that much homoplasy is present in Ensifera, particularly in acoustic structures." They considered that tegmen stridulation and tibial tympanae are ancestral to Ensifera and have been lost on multiple occasions, especially within the Gryllidae.[33]

The patrons, and other players from the social class known as the "gentry", began to classify themselves as "amateurs"[fn 1] to establish a clear distinction vis-à-vis the professionals, who were invariably members of the working class, even to the point of having separate changing and dining facilities.[29] The gentry, including such high-ranking nobles as the Dukes of Richmond, exerted their honour code of noblesse oblige to claim rights of leadership in any sporting contests they took part in, especially as it was necessary for them to play alongside their "social inferiors" if they were to win their bets.[30] In time, a perception took hold that the typical amateur who played in first-class cricket, until 1962 when amateurism was abolished, was someone with a public school education who had then gone to one of Cambridge or Oxford University – society insisted that such people were "officers and gentlemen" whose destiny was to provide leadership.[31] In a purely financial sense, the cricketing amateur would theoretically claim expenses for playing while his professional counterpart played under contract and was paid a wage or match fee; in practice, many amateurs claimed somewhat more than actual expenditure and the derisive term "shamateur" was coined to describe the syndrome.[32][33]

Additional runs can be gained by the batting team as extras (called "sundries" in Australia) due to errors made by the fielding side. This is achieved in four ways: no-ball, a penalty of one extra conceded by the bowler if he breaks the rules;[108] wide, a penalty of one extra conceded by the bowler if he bowls so that the ball is out of the batsman's reach;[109] bye, an extra awarded if the batsman misses the ball and it goes past the wicket-keeper and gives the batsmen time to run in the conventional way;[110] leg bye, as for a bye except that the ball has hit the batsman's body, though not his bat.[110] If the bowler has conceded a no-ball or a wide, his team incurs an additional penalty because that ball (i.e., delivery) has to be bowled again and hence the batting side has the opportunity to score more runs from this extra ball.[108][109]
Crickets have a cosmopolitan distribution, being found in all parts of the world with the exception of cold regions at latitudes higher than about 55° North and South. They have colonised many large and small islands, sometimes flying over the sea to reach these locations, or perhaps conveyed on floating timber or by human activity. The greatest diversity occurs in tropical locations, such as in Malaysia, where 88 species were heard chirping from a single location near Kuala Lumpur. A greater number than this could have been present because some species are mute.[1]
The captain is often the most experienced player in the team, certainly the most tactically astute, and can possess any of the main skillsets as a batsman, a bowler or a wicket-keeper. Within the Laws, the captain has certain responsibilities in terms of nominating his players to the umpires before the match and ensuring that his players conduct themselves "within the spirit and traditions of the game as well as within the Laws".[58]

Cricket flour may be used as an additive to consumer foods such as pasta, bread, crackers, and cookies. The cricket flour is being used in protein bars, pet foods, livestock feed, nutraceuticals, and other industrial uses. The United Nations says the use of insect protein, such as cricket flour, could be critical in feeding the growing population of the planet while being less damaging to the environment.[58]
