Supersonus can hit the high notes. One species in this newly discovered genus of katydid hailing from the rainforests of Ecuador and Colombia can produce mating calls of a higher pitch than previously recorded for any arthropod, a vast group that includes insects and spiders. Usually katydids produce calls between 5 kHz to 30kHz--meaning that humans, who can hear up to 20 kHz, can enjoy the singing of some species. But the three new species in this group are unique, producing calls as high as 150 kHz, far beyond what you and I can hear (unless you are a human-bat hybrid). Find out more from Popular Science.
