Atlas Moth

Attacus atlas

The atlas moth (Attacus atlas) is one of the world's largest moths by wing area, native to tropical and subtropical forests of South and Southeast Asia. Its broad reddish-brown wings have translucent patches and wingtips that can resemble snake heads when the moth is resting. Adults do not feed because their mouthparts are not functional; they live briefly on energy stored from the caterpillar stage and focus on mating and egg-laying.

Atlas moths are kept mainly by insect breeders, educators, and butterfly houses. Successful rearing depends on fresh host plants for caterpillars, clean sleeves or rearing cages, good ventilation, and humidity that allows safe molting without encouraging mold. Larvae spin tough silk cocoons before pupating, and adults need space to expand their wings after emergence. They are display insects, not handling pets. Because eggs, larvae, and pupae may be regulated in trade, breeders should confirm local import and plant-pest rules before shipping them.
