The Atlas moth (Attacus atlas) is one of the largest moths in the world, with a wingspan of over 9.8 inches. Females are slightly larger than males. Like other moths in the family Saturniidae, adults do not have working mouth parts and only live for a few days to a week.
Although there are more than 20 species and subspecies in the genus Attacus, the Atlas moth is a native to the tropical and subtropical forests of Southeast Asia. They are cultivated in some areas for their silk called fagara, which is rough and woolly.
