The Atlas moths of Southeast Asia are considered the largest moths in the world in terms of total wing surface area [upwards of c. 400 cm2 (62 sq in)]. Their wingspans are also amongst the largest, from 25–30 cm (10–12 in). Females are appreciably larger and heavier.
Atlas moths are said to be named after either the Titan of Greek mythology, or their map-like wing patterns. In Hong Kong the Cantonese name translates as “snake’s head moth”, referring to apical extension of the forewing, which bears a passing resemblance to a snake’s head. This is easily seen in the photo above.
