Davey, P., 2009: A species restricted to south-east Britain, the larva feeding on the flowers and seeds of common couch (Elytrigia repens) and cock's-foot (Dactylis glomerata). In Dorset, the moth seems to be increasing in unimproved grassland habitat generally following lean times more than fifty years ago. It is locally common along the coast and locally abundant on chalky soils inland. In such places, it is a highly visible species during the day as it rests on the flower heads of knapweed (Centaurea spp.) or field scabious (Knautia arvensis). There are more than forty light trap records across the Poole Basin on sandy soil, and dispersal is suspected for many of them.
