Davey, P., 2009: A species with a general distribution in Britain, the larva feeding on blackthorn (Prunus spinosa), alder (Alnus glutinosa), birch (Betula spp.), plum (Prunus domestica) and apple (Malus domestica). In Dorset, the moth is local and at low density, most frequently found in blackthorn scrub, and in town gardens and orchards where fruit trees grow. Roughly two thirds of all Dorset records are from West Bexington amongst the blackthorn thickets at the site. Singletons from river systems and swamp habitat suggest colonisation also of alder.
