Attacus atlas

Attacus atlas, the Atlas moth, is a large saturniidmoth endemic to the forests of Asia. The species was described by Carl Linnaeus in his 1758 .

The Atlas moth is one of the largest lepidopterans, with a wingspan often measuring from 250mm to 300mm. and a wing surface area of about 160 cm (25 in). It is only surpassed in wingspan by the white witch (Thysania agrippina) and Attacus caesar, and in wing surface area by the Hercules moth (Coscinocera hercules). As in most silk moths, females are noticeably larger and heavier than males, while males have broader antennae.
