Supersonus

Genus of katydids

Supersonus is a genus of katydids in the order Orthoptera first described in 2014. The genus contains three species which are endemic to the rainforests of South America. Its name is an allusion to the fact that the males, in order to attract the females, produce a very high frequency noise which can reach 150 kHz. This has been considered the highest frequency ultrasonic noise of the animal kingdom. The noise is imperceptible to human hearing, which is only capable of detecting up to 20 kHz.
