The Atlas Moth (Attacus atlas) is one of the largest species of moth and is endemic to the forests of Asia. It has a wingspan that can measure up to 9.4" with the females being larger than the males. The only moths that are bigger than the Altas are the White Witch, Attacus Ceaser and Hercules moths.
These moths are born without mouths with the sole purpose to mate. They will live off stored fat while they search for a mate, mainly by females releasing pheromones into the air to attract the males, so they only live for one to two weeks. Their silk can be used but is not as great as other insects, so it is not used in a commercial capacity.
