Davey, P., 2009: A widespread species in England and Wales, more local in Scotland, the larva feeding on birch (Betula spp.) and alder (Alnus glutinosa), and occasionally other deciduous trees. In Dorset, the moth is frequent on birch-rich heathland on sandy soils, in woodland containing mature birch or alder on any soil, and among alder-rich fen, swamp and river valleys. The few individuals trapped away from birch and alder suggests dispersal. A single old record of larvae found on western balsam-poplar (Populus trichocarpa) demonstrates that the species may sometimes occupy alternative habitats. Although the moth is single brooded in the UK during late May and June, two brood cycles, similar to that of Poplar Grey2278, is suspected.
