    A Myotis volans bat echolcates and attacks insects. The bat captures moths using its entire wing surface, bringing the prey into its tail membrane, then into its mouth. Sometimes it doesn't like what it catches and drops the moth, other times the bat misses. But when it goes right, the bat flies away, while echolcating and eating its reward.

    A long-legged Myotis bat echolocates among flying insects. See the bat open its mouth to emit each echolocation call. This video was taken at 1000 frames per second and slowed 30 times. Audio was also slowed 30 times, naturally dropping the pitch so we can hear the bat sonar pulses.

    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.
