Tiger moths use acoustic signals to tell bats “stay away, I’m toxic!”

TIL that tiger moths have evolved a clever way to avoid being eaten by their biggest predators, bats. Storing up toxins (cardiac glycosides) from the plants they feed on as larvae make them “highly unpalatable” (read: disgusting). That’s cool in and of itself, but these moths take it a step further. This study shows that the moths use special organs called “tymbals” to broadcast sounds. Tymbals are related to the sound organs of cicadas, but tiger moths use the sounds like other species use brig
