Davey, P., 2009: A widespread species in Britain, the larva feeding on hazel (Corylus avellana), birch (Betula spp.) and hornbeam (Carpinus betulus). In Dorset, the moth is locally abundant in oak and ash woodland on chalky soils where hazel is the dominant understorey shrub. The moth is seldom encountered far from hazel-rich habitat, in fact the absence of records from areas where birch is dominant suggests that birch is not a potential foodplant for the species in the county. Occasional short to medium range dispersal is evidenced by an individual trapped at West Bexington on 26 June 1995 (R Eden) during a north-easterly airflow. The national norm is for a partial second brood, but in Dorset the moth appears to be double-brooded. The first brood is, on average, three times larger than the first.
