Davey, P., 2009: A widespread species in England and Wales, more local in Scotland, the larva feeding on the lower stems and roots of common couch (Elytrigia repens) and cock's-foot (Dactylis glomerata). In Dorset, the moth is common in unimproved grassland, arable, garden and verge habitat. It ranges from locally abundant in undercliff situations on the coast and on unimproved grassland on chalky soils inland, to rare on heathland. The moth is single brooded between mid-May and early July, however, in Dorset, a partial second brood has been noted from late July and into August in eleven of the past twenty years.
Of the three similarly-marked 'Minors' this is the most common, and ideally should be determined via dissection. Diagnostics include: a deeply indented basal part of the post-median fascia; the species having the most contrast, usually. | Determination by Genitalia Examination (gen. det.) Required | |
