On this page you can see and hear the calling and courtship songs of Gryllus texensis and Gryllus rubens.

G. texensis and G. rubens are sister species of field cricket, best distinguished by song. There is no other known way to distinguish the males of these species.

Their calling song is a trill composed of many pulses. The major song difference is pulse rate.
