The moth genus containing the atlas moth is Attacus.
Attacus is a genus of giant silk moths in the family Saturniidae. Its best-known member is the atlas moth, Attacus atlas, native to parts of South and Southeast Asia. Atlas moths are recognized by their broad wings, patterned surfaces, and forewing tips that resemble the heads of snakes.
The atlas moth is often described as one of the largest moths by wing area. Comparisons can vary depending on whether researchers measure wingspan or total surface area, so claims about the single largest moth should be read carefully.
Like many giant silk moths, adults have reduced mouthparts and usually live mainly to reproduce. Their caterpillars feed on plant leaves before forming a substantial silken cocoon.
