Jamming isn’t the only possible explanation for moth noises, he said. As Conner puts it, “Why would you do that to a bigger, more dangerous predator that’s going to eat you?” As other moth species silently flee when they hear the sonar pings of an incoming bat, tiger moths generally click back. ![]() Tiger moths, a group of some 11,000 species, have been intriguing candidates because they present a puzzle in battlefield behavior. “There was some tantalizing neurophysiological work.” But to collect behavioral evidence to demonstrate jamming, he said, takes the right moth. “This is warfare … The first counter-adaptation is that the insects developed ears.”īiologists have debated the possibility that moths could also evolve sounds that sabotage bat sonar. Insect-hunting bats and their moth prey have become a classic in the study of evolutionary arms races, Conner says. Conference attendee David Yager of the University of Maryland in College Park says Conner’s experimental paradigm is “very strong, and I do think he has documented jamming by a species of moth.”
