Attacus atlas, the Atlas moth, is a large saturniid moth endemic to the forests of Asia. The species was described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. 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 cm 2 (≈25 in 2). [2]

As the larvae attain a size of about 4.5 inches, they form 7-8 cm long silken cocoons among plant leaves to metamorphose as pupa, and attach the same to the twig with the help of a fine, silken string. The chrysalis spends about a month inside their cocoons, after which they are reborn as atlas moths, breaking out of the cocoon.

Pupa. Once the larvae are 11.5 cm long, they are ready to pupate. The pupal phase takes place inside a cocoon made of desiccated leaves held together with silk produced by the larva. The cocoon is 7-8 cm long. It takes about four weeks for the adult moths to evolve out of the cocoon.

Attacus atlas is most popularly called the "atlas moth" but is also called the "empire silkworm" after its large size or the "fagara silkmoth" after the fagara silk that is obtained from its cocoons (Peigler, 1983).
