Comet moth

The Comet moth is a large North American silkmoth easily identified by its bright yellow wings and incredibly long tails on its hindwings. These distinctive tails can extend up to twice the length of its actual body. As a member of the Saturniidae family, it is a large and visually striking insect.

This specific silkmoth is endemic to the southeastern United States, particularly thriving in deciduous forests. The adult moths are typically spotted flying during the late spring and early summer months. They rely heavily on the sweetgum and maple trees in this region to feed their caterpillars.

Lepidopterists study the comet moth because its long tails serve as an evolutionary defense mechanism against bats. When a bat uses echolocation to hunt the moth, the spinning tails create confusing echoes that jam the bat's sonar. This effectively tricks the predator into attacking the tail rather than the moth's main body.

Like many other moths in the Saturniidae family, adult Comet moths do not have functional mouthparts and cannot eat. As a result, their adult lifespan is extremely short, typically lasting only about one week. Their sole purpose during this brief period is to mate and lay eggs before exhausting their energy reserves.
