Davey, P., 2009: A species occurring in England and Wales, the larva feeding on birch (Betula spp.), hazel (Corylus avellana), hawthorn (Crataegus spp.), oak (Quercus spp.), sweet chestnut (Castanea sativa) and bilberry (Vaccinium myrtillus). In Dorset, the moth is at low density in deciduous birch-oak woods on chalky soils such as Stubhampton Bottom and Chetterwood, and on clay soils such as Piddles Wood, Yellowham Wood and Boys Wood. Adults may be flushed out from hazel understory in these localities. The moth also occurs in deciduous birch and sweet chestnut woodland on sandy soils such as Arne Wood and Whitesheet. Although there is partial emergence in May, the main flight period for the species is June and July which is later than the national norm of May and June; a partial bivoltine cycle is suspected in Dorset.
