Davey, P., 2009: A common lowland species in England and Wales, becoming more local in Scotland, the larva feeding on the lower stems and roots of cock's-foot (Dactylis glomerata) and other grasses. In Dorset, the moth is widespread and frequent, and occupies most habitats apart from heathland. It is common on unimproved grassland, and is frequent in woodland containing open grassy rides.

Of the three closely related 'Minors', this is the most widespread. Diagnostics include: the darkest 'Minor'; a brassy or coppery sheen across the forewing; orbicular and reniform stigmata indistinct.
