The Comet Moth, or Madagascar Moon Moth, is one of the largest silk moths in the world. He can measure up to twenty cm across. Like many moths, he spends the majority of his life - about two months - as a caterpillar before pupating. His natural habitat is the rainforest, and the cocoon is riddled with holes to allow for drainage and prevent the pupae from drowning. Once he has hatched he is incapable of eating, and will only survive for 4-5 days. His main aim is to reproduce. Female Comet Moths can lay over 120 eggs. Like many Madagascan creatures, the Comet Moth is threatened by deforestation, but he does readily reproduce in captivity.
