The Transition from Leg to Wing Stridulation in Two Geographically Distinct Populations of the Grasshopper Stenobothrus rubicundus

摘要

In many orthopteran insects, sound production by moving the wings or the hindlegs has evolved as an elaborate in-traspecific communication. Crickets and katydids rub the elytra against each other, some acridid grasshoppers produce a rattling noise with their hindwings during flight, and many others strike the hindlegs sonorously against the forewings. Knowing that different appendages are used, it is not obvious that wing and leg Stridulation might share common mechanisms.
