Fairly common in Europ.
The female is larger than the male, and has a large tuft of yellow hairs at the tip of her abdomen, which is used to cover the newly-laid eggs.
Adults have a silky white appearance. Both sexes have a white body with a yellow anal tuft, which is often visible when the moth is at rest. The males have a small dark mark on the tornal aspect of the forewing. The hindwings are pale, silky-white.
Key Identification Features:
* Silky-white appearance
* Yellow anal tuft
* Dark-coloured marks on the lower aspect of the forewing (males only)
It flies in July and Octuber.
The caterpillars, in common with many of the Lymantriidae, are covered with irritating hairs and should only be handled with extreme care. They feed on a number of deciduous trees and shrubs.
The colourful larvae, which have the characteristic hump on the first segment, are gregarious during early instars. They are best looked for during the latter part of summer, prior to hibernation, on Hawthorn Crataegus monogyna, willow Salix spp., oak Quercus spp., and possibly other trees. It overwinters as a small larva.
