It is endemic to the United States and is the largest cricket in North America. Its natural habitat is temperate grassland. It is threatened by habitat loss and is currently only found in Oklahoma, Kansas, Missouri and Arkansas. Males of this species produce sounds by rubbing their forewings together. They sing from special burrows they construct in the prairie soil to attract females for mating, and they can be heard at distances up to 400 meters from the burrow. Males aggregate their acoustic burrows in a lek arena and are very sensitive to vibrations carried through the ground. Males communicate with neighboring males through vibrational signals, and the songs they project to flying females are harmonic chirps, rather than the trills produced by most mole crickets. ==Physiology== The prairie mole cricket (''Gryllotalpa major'' Saussure) is the largest of the North American crickets, measuring up to 5 cm long, weighing up to 2.6g, and typically brown to reddish-brown in color.〔) />〔)>〕 Like other mole crickets (Gryllotalpidae), ''G. major'' has a bullet-shaped, heavy pronotum and large robust forelimbs used for digging complex subterranean burrows.〔)>〕 Like other Orthoptera males of the species have modified forewings with a stridulatory apparatus which they use in conjunction with acoustic burrows to perform an acoustic sexual advertisement call to attract females during their brief mating season beginning in late spring.〔) />〔) />〔)>〕 Research by Nickle & Carlysle 〔)>〕 found that females of ''G. major'' have similar stridulatory files as males, though smaller and weaker, and they are in fact capable of producing sound, though it seems the sound serves no function in other species sound production by females is linked to aggression and defence. Howard et al.〔)>〕 did a study on the hearing sensitivity of ''G. major'' and found that they have hearing sensitivities from 2 kHz to an ultrasonic range at 25 kHz. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gryllotalpa major」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
