Moth Making Sonar Jamming Sounds Add Video

This is how the tiger moth Bertholdia trigona makes sound to jam bats. The structure is called a tymbal. On it there is a series of about 30 ridges that collapse inward and outward. As each ridge collapses it produces a very brief, high-pitched click. This moth can click at up to 4500 clicks per second! This is necessary to make sure clicks occur at the same time the bat is listening for echoes, and this "jams" the bat. Credit: Aaron Corcoran and Nickolay Hristov.
