Davey, P., 2009: A widespread species in south-eastern England, local in Wales, central and eastern England, and absent elsewhere, the larva feeding on tufted vetch (Vicia cracca). In Dorset, the moth is widespread but local and at low density, but common on unimproved grassland on ill-drained clay soils containing areas of tall sward. In this habitat, meadow vetchling (Lathyrus pratensis) or dyer's greenweed (Genista tictoria) may host the moth. A record of a potential second brood example follows: Hurn, at MV light on 16 September 2006 (M Jeffes).
