Species Account

For further information refer UK Moths.

Davey, P., 2009: A widespread species in Britain, the larva feeding on various grass species such as cock's-foot (Dactylus glomerata), common couch (Elytrigia repens), meadow grass (Poa spp.) and fescue (Festuca spp.). In Dorset, the moth is common on Portland and frequent very locally on unimproved chalk grassland sites but decreasing; occasional singletons appear in other open habitats but it is virtually absent from woodland. The species has evidently declined since the middle of the last century; "generally distributed and more or less common generally." (W Parkinson Curtis).
