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. 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. 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. 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.
The wings lie flat on the body and are very variable in size between species, being reduced in size in some crickets and missing in others. The fore wings are elytra made of tough chitin, acting as a protective shield for the soft parts of the body and in males, bear the stridulatory organs for the production of sound. The hind pair is membranous, folding fan-wise under the fore wings. In many species, the wings are not adapted for flight.
Other defensive strategies are the use of camouflage, fleeing, and aggression. Some species have adopted colourings, shapes, and patterns that make it difficult for predators that hunt by sight to detect them. They tend to be dull shades of brown, grey, and green that blend into their background, and desert species tend to be pale. Some species can fly, but the mode of flight tends to be clumsy, so the most usual response to danger is to scuttle away to find a hiding place.
Crickets have from time to time appeared in poetry. William Wordsworth's 1805 poem The Cottager to Her Infant includes the couplet "The kitten sleeps upon the hearth, The crickets long have ceased their mirth". John Keats's 1819 poem Ode to Autumn includes the lines "Hedge-crickets sing; and now with treble soft / The redbreast whistles from a garden-croft". The Chinese Tang dynasty poet Du Fu (712–770) wrote a poem that in the translation by J. P. Seaton begins "House cricket ... Trifling thing. And yet how his mournful song moves us. Out in the grass his cry was a tremble, But now, he trills beneath our bed, to share his sorrow."
