Davey, P., 2009: A local species in England and Wales, the larva feeding on birch (Betula spp.), alder (Alnus glutinosa) and other deciduous tree species. In Dorset, the moth is generally at low density, but frequent locally along river valleys or in fens and swamps containing alder, and in old damp deciduous woodland on clay soils. Although it has been recorded from birch-rich localities, instances are surprisingly few from any single site considering birch is a quoted foodplant, and it does appear that alder is preferred by the moth, at least in the county. The following examples are possible partial second brood moths: Iwerne Minster, at MV light on 27 August 1967, 14 September 1967 (H Moore).
