Davey, P., 2009: A species occurring on heaths and moorland throughout Britain, the larva feeding on the flowers of heather (Erica spp.). In Dorset, the moth is abundant on sandy soil where heather (Calluna vulgaris) and heath (Erica spp.) abound. The moth is also encountered occasionally on unimproved dry grassland inland and on the coastal belt well away from heathland where ericaceous plants are quite absent, for example between 1991 and 2004, there were twenty separate occasions when the moth was trapped at West Bexington. Dispersal from sandy soils is likely although numbers are at times amazingly high: Badbury Rings, thirty at MV light on 7 July 2002 (P Davey). The national norm is a partial double brood, but in Dorset the moth is double brooded and the peak of the second brood is on average, twice as large as that of the first.
