Do the Assas Stritulate Their Genitals?

In a predator prey relationship where the predator is like looking for the prey, the prey will do things visually. So obviously, if bats are navigating using sonar, their prey would respond using sound. The males of these moths stritulate their genitals really quickly and in flight. But when they hear the sound of a bat coming, they just tritulate their genitals, and it just goes crazy. It essentially jams the sonar of the bats, and they can't actually locate the moth.
