Davey, P., 2009: A local species in England, Wales and southern Scotland, the larva feeding on the lower stems and roots of cock's-foot (Dactylis glomerata) and other grasses. In Dorset, the moth ranges from rare on sandy soil to common on chalky soils. It is equally common on unimproved grassland, scrub or grassy rides in open woodland on chalky soils. The species has also been found in river and fen habitat, notably on the River Frome, the River Piddle and on Bere Stream. In this wetland habitat, reed-canary grass (Phalaris arundinacea) and reed sweet-grass (Glyceria maxima) may be host food-plants. It is largely absent from heathland.

Diagnostics include: a vinous-red colouration on the central band of the forewing; orbicular and reniform stigmata pale and distinct against the plum-coloured median band.
