Davey, P., 2009: A widespread and common species in Britain, although less common in northern Scotland, the larva feeding on gorse (Ulex spp.), petty whin (Genista anglica), dyer's greenweed (Genista tinctoria) and broom (Cytisus spp.). In Dorset, the moth is common on heaths and downs where gorse abounds, and in unimproved grassland habitat where dyer's greenweed flourishes at Rooksmoor in the Blackmore Vale. Larvae have also been found on broom at Parley Common and along the Wimborne by-pass.
