Erebidae, Lymantriinae Wingspan (Males):36mm, (Females): Wingless.

Females are sedentary, and stay on the cocoon after emergence. Flying Males can home in to the pheromones released by the Females, and will instantly mate with a free Female. Once fertilised, the Females lay rows of eggs onto the surface of the cocoon. She will be repeatedly mated (as above) until all eggs are laid, and she then expires.
