No, your eyes are not deceiving you. Some moths have evolved the ability to make noise at bats using their genital structures.

And apparently it's so useful that this ability has emerged, separately, again and again in different species of hawkmoths.

According to new research, these moths have evolved the ability to scream at bats using their genitals independently as many as seven times over 30 million years – and at least three distinct anatomical mechanisms have emerged, producing different kinds of potentially sonar-jamming ultrasound.

That's evolution. If it works... The repeated area being used is probably because of the location. And it's not that they evolved it by choice, but rather:

"Harry makes weird noises out his rear end."

All the moths laugh at Harry.

Later, Harry doesn't get eaten and finds a mate, all because bats find him more annoying to track.
