Davey, P., 2009: A local species restricted to the south of Britain, the larva feeding on bilberry (Vaccinium myrtillus), bramble (Rubus fruticosus), and dog rose (Rosa canina). In Dorset, the moth is local and at low density. Its primary but restricted habitat is bilberry growing in old woods and on dry ridges on acid soils around the periphery of the Poole Basin; its secondary habitat is scrub containing dog rose or bramble across the chalk belt in the north-east of the county. Reduction in old oak and birch woodland on sandy soil with attendant soil disturbance, plus loss of scrub from chalky soil has undoubtedly negatively impacted this species across the county. It is recommended that this species be included in management plans that apply to oak and birch woodland hosting bilberry, and in management plans that apply to unimproved grassland on chalky soils containing viable areas of scrub.
