Hawkmoths are now the second known species of moths that have found a way to jam bat sonar. Moths have evolved other defense mechanisms to detect and avoid bats.

In the dark caves and jungles of the world, there's an epic 65-million-year evolutionary battle going on between bats and moths.
Moths are obviously the underdogs. But scientists are learning that moths have found ingenious ways to counter the weapons of the bat.
The latest discovery is that the hawkmoths may be jamming the sonar signals bats use to track and catch moths in flight. How do they do it?
According to an article in Nature, behavioral ecologist Jesse Barber of Boise State University in Idaho and phylogeneticist Akito Kawahara of the University of Florida in Gainesville went to Borneo to study how hawkmoths defend themselves.
