In the above Vine from the Berkshire Museum exhibit “Butterflies,” you can catch a glimpse of the ginormous Attacus atlas, the world’s largest moth. Atlas Moths are found in the tropical and subtropical forests of Southeast Asia and are common across the Malay archipelago. The female Atlas Moth, which is appreciably larger than the male, may have a wingspan of up to ten inches-imagine, nearly a foot! Attacus atlas is a member of the Saturn Family of moths, as are the North American Luna and Cecropia Moths. For comparison sake, our gorgeous Cecropia Moth has a wingspan of up to six inches.
