Gryllus bryanti is among the larger species of field crickets. Body colour is dark brown with reddish brown around the head, thorax and legs (see images of male and female on this page).[2]
Habitat
Typical of many field crickets, G. bryanti can be found living in cracks or burrows in the ground in disturbed areas (e.g. near roads) and around human habitations.[2]
Song production
Like most gryllids, males produce song by tegminal (forewing) stridulation.[3] Male G. bryanti calling song is distinct from other species of Gryllus in that each chirp consists of only a single pulse (wingstroke) instead of multiple pulses (see image of calling song on this page).[1][2] Courtship song contains high frequency ticks interspersed amongst lower frequency pulses (see image of courtship song on this page).[2]
