Davey, P., 2009: A species occurring throughout England and Wales, becoming scarcer in Scotland, the larva feeding on blackthorn (Prunus spp.), hawthorn (Crataegus spp.), oak (Rubus fruticosus), sallow (Salix spp.) and other deciduous trees and shrubs. Like the Brown-tail2029, the hairs of the larva can inflict a rash on unprotected skin when handled. In Dorset, the moth is widespread and usually common, and rises to abundant in deciduous woodland, or where hawthorn and blackthorn grow in thickets. The national norm is for a single brood in July and August, however, occasional second brood moths emerge during Septembers and Octobers that follow warmer than average summers, for example, 1976, 1995, 2003 and 2006.
