Calliteara pudibunda (Pale Tussock) §5 male
ID: Both C.pudibunda and Dicallomera fascelina (Dark Tussock) have a characteristic resting posture with the hairy forelegs stretched out in front of the head; both have strongly bipectinate antennae in the male, shortly bipectinate in the female and in both the female is larger and paler than the male. D.fascelina flies Jul-Aug and is largely confined to heath, moor and coastal shingle; it usually shows some orange blotches in the cross-lines and the male has grey antennae. In C.pudibunda the cross-lines lack orange; in the male the median fascia is contrastingly dark and the antennae are orange-brown. Melanism is fairly common in the male, less so in the female.
