What is the largest species of butterfly?

The largest species of butterfly is the Atlas moth (Attacus atlas), which has a wingspan of up to 30 centimeters (12 inches). Native to the forests of Southeast Asia, the Atlas moth is known for its large, striking wings, which have a pattern resembling snake heads. Despite their size, Atlas moths are gentle and do not feed as adults, as they lack functional mouthparts. Their main goal is to mate and lay eggs on specific host plants like the mulberry tree.
