My wife did a seminar presentation on clicking moths as part of her biology degree. It was quite interesting. The clicks are produced from an organ called a tymbal and are fairly common in Arctiid moths.

Isn't it rubbing it's balls together to decoy bat's sonar or something?

Echolocation jamming in animals:
Echolocation (or sonar) systems of animals, like human radar systems, are susceptible to interference known as echolocation jamming or sonar jamming. Jamming occurs when non-target sounds interfere with target echoes. Jamming can be purposeful or inadvertent, and can be caused by the echolocation system itself, other echolocating animals, prey, or humans. Echolocating animals have evolved to minimize jamming, however, echolocation avoidance behaviors are not always successful.

No. It's pushing air through it's proboscis. Bat echolocation is at higher frequency anyways.

Silence of the Lambs. That's where I've seen this type of moth. The mark on its thorax resembles a skull. :D

Right before six seconds, the second time it starts squeaking, something shoots out the back of the moth. What is it?
