Davey, P., 2009: A rare species in Britain found only in the Breck district where populations have declined to the point of extinction since the 1960s, the larva feeding on mugwort (Artemesia vulgaris). Abroad the species additionally feeds on beet (Beta vulgaris), goosefoot (Chenopodium spp.), medick (Medicago spp.) and clover (Trifolium spp.).
In Dorset, the moth has been recorded on sixteen occasions in recent years, and mostly from coastal sites; the earliest county record was from 1872. The species is therefore an infrequent immigrant to Dorset, and a north-European source is likely for most of the examples seen.
