Davey, P., 2009: A local species in Britain, commonest in the south-east, scarcest in the north, the larva feeding on various deciduous trees, and in the north on bilberry (Vaccinium myrtillus) and heather (Calluna vulgaris). In Dorset, the moth has become distinctly local, at low density and declining across its remaining two distinct biotypes. These are dry heathland on sandy soil, for example at Arne and at Matchams, and unimproved grassland on chalky soil, for example inland on Melbury Down, and on the coast at St Albans Head. The following old records suggest also a preference for old birch/oak woods: Milton Abbas, abundant (O Leigh Wood), Bere Wood and Bloxworth, sometimes abundant (O Pickard Cambridge, W Parkinson Curtis), Cranborne, common (F Fisher, W Parkinson Curtis). All three biotypes are relatively close together at Furzebrook where two hundred moths were trapped between 1972 and 1976.
