Supersonic Lover

Yowch. Supersonus is newly discovered genus of katydids that includes three species that sing at the highest known frequencies of any known insect, spider, or other arthropod. Male katydids sing to attract female katydids, but at these frequencies, they would be difficult for other species to hear. That’s a good thing. Researchers think the high frequencies likely help Supersonus katydids from being overheard by predatory bats.
