Davey, P., 2009: Local in England and Wales, the larva feeding on the calyx of hawthorn (Crataegus monogyna) hips, and oak (Quercus spp.). In Dorset, the moth is common where hawthorn abounds and is frequent in oak woods. The national norm is a single brood in May and early June, but in Dorset the first brood is on the wing from mid-April until the end of May. A partial second generation occurs in mid-summer, with regular records from Puddletown, Merley and Trigon in recent years.
