Davey, P., 2009: A widespread species in southern Britain and rare in Scotland, the larva feeding on various grasses, herbaceous plants and hawthorn (Crataegus spp.). In Dorset, this highly variable moth is widespread and ranges from abundant on unimproved grassland on chalky soils, although numbers vary enormously from year to year, to common on dry, grassy heathland, and finally to low density in woodland.

Certain forms of this moth can be similar to the Brown-spot Pinion2266. Diagnostics include: lacks pitch-black marks along costal edge of forewing.
