Atlas Moth / Attacus atlas

Photographed in the ENMAX Conservatory at the Calgary Zoo yesterday afternoon, 21 August 2012. There was a rack with a number of pupa hanging from it and a couple of these emerged Atlas Moths. They are incredible, huge Moths, but I never seem to get a photo of one that I am happy with, ha. Always fascinated by their amazing antennae and their unusual legs.

"Atlas moths are considered to be the largest moths in the world in terms of total wing surface area (upwards of c. 400 square cm or 65 square inches). Their wingspans are also amongst the largest, from 25-30 cm (10-12 inches). Females are appreciably larger and heavier .... The Atlas moth (Attacus atlas) is a large saturniid moth found in the tropical and subtropical forests of Southeast Asia, and common across the Malay archipelago"
