How big is the Atlas Moth?

The Atlas moth is one of the largest lepidopterans, with a wingspan measuring up to 24 cm (9.4 in)[1] and a wing surface area of about 160 cm2 (≈25 in2).[2] It is only surpassed in wingspan by the white witch (Thysania agrippina) and Attacus caesar,[1] 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.[3][4][5]
