Davey, P., 2009: A species of grassland, more frequent in the east of Britain that the west, the larva feeding on various soft-bladed grass species. In Dorset, the moth is common on undercliff grassland on Portland and locally frequent on unimproved grassland on chalky soils throughout. The moth is also frequent in garden habitat in Poole. In all these situations the host plants are likely to be common couch (Elytrigia repens) and cock's-foot (Dactylis glomerata). Elsewhere, the moth is rare and is virtually absent from heathland and core woodland. The species has evidently declined on Purbeck and on Portland due to the overall improvement and loss of coastal grassland; its status historically was assessed as abundant in both regions. An unusually dark melanistic specimen, possibly ab. unicolor, was trapped at Scar Bank by A Russell.
