Davey, P., 2009: A local species in England and Wales, the larva feeding on oak (Quercus spp.), birch (Betulua spp.) and alder (Alnus glutinosa). In Dorset, the moth is local among old oak/birch and oak/alder woodland where it is at low density; singletons have been noted where old oaks grow in open situations such as parkland, or along old field boundaries. Typical woodland sites where it may be found include Boys Wood, Powerstock Common, Oakers Wood, Castle Wood and Chase Woods. Although the moth is single brooded in June and July, the species has occasionally been recorded at light traps from late August and into September.
