Which moth is famous for having wings patterned like a snake’s head?

The Atlas moth is famous for having forewings patterned like snake heads.

Attacus atlas is a large saturniid moth native to parts of Asia. At the tips of its forewings, the outline and markings can resemble the head of a snake. When the moth moves its wings, the illusion may startle or confuse predators, giving the insect a chance to escape.

The Atlas moth is also notable for its size. It has a large wingspan and broad wing surface, although measurements vary among individuals and sources. Its wings are usually reddish-brown, tan, and purple-gray, with translucent windows bordered by darker veins.

Adults have reduced mouthparts and generally do not feed. They rely on energy stored during the caterpillar stage, so their adult lives are focused mainly on reproduction. The species is sometimes confused with other giant silk moths, but the snake-head wing tips are its most recognizable feature.
