3-D imaging reveals four extraordinary cases of convergent evolution of acoustic communication in crickets and allies (Insecta)
Abstract When the same complex trait is exhibited by closely related species, a single evolutionary origin is frequently invoked. The complex stridulatory apparatus present in the forewings of extant crickets, mole crickets, katydids, and prophalangopsids, is currently interpreted as sharing a singl...
