Atlas Moth

Atlas moths are considered the largest moths in the world in terms of total wing surface area [upwards of 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 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.
