Worlds Weirdest Moth's

The Atlas moth (Attacus atlas) is considered the world’s largest moth by total wing surface area. The moth’s cocoon is so large that it’s used as a lucky charm in Africa, pocket purses in Taiwan and ankle rattles in Mexico.

Large as it is, like the Luna moth, the adult Atlas moth has no mouth and cannot eat throughout its one to two weeks life (it does all its eating in the larva stage). via: Neatorama
