Came home and found this on the wall on my house. Thing of beauty.
The Atlas moth (Attacus atlas) is a large saturniid moth found in the tropical and subtropical forests of Southeast Asia, and is common across the Malay archipelago.
Atlas moths are considered the largest moths in the world in terms of total wing surface area, reaching upwards of c. 400 cm2 (62 sq in). Their wingspans are also amongst the largest, reaching over 25 cm (10 in). Females are appreciably larger and heavier.
Atlas moths are predominantly tawny to maroon in color with roughly triangular, diaphanous “windows” on both forewing and hindwing, bordered in black. The purpose of these gossamer portals is not clear, but light and shadow play over the surface, giving the impression of movement, and are thought to play a role in predator avoidance. J. Patrick Malone first pointed out that the Atlas moth is the only insect species to successfully mimic a predatory reptile as a means of defense, as demonstrated by the image of the Malaysian tree snake at the upper most distal aspects of their wings. Such a large insect would typically represent excellent prey, but the image of one or two snakes waving back and forth, poised for a strike, likely dissuades many predators. The Atlas moth body is covered in a chitin-based hair, more properly called seta (pl. setae) and are stiff enough to be an irritant to skin and mucosal tissues of some animals. Their length is disproportionately short, compared to wing structure, but their stout middle and third segment, or mesothorax and metathorax respectively, provides the internal dimensions necessary for flight muscle attachment and coordination. Patterns and coloration vary among the many described subspecies. Male Atlas moths are distinguished from females by their smaller size, more tapered wings, and larger, bushier antennae
