Davey, P., 2009: A widespread and often common species in Britain, the larva is polyphagous on deciduous trees and shrubs. In Dorset, the species is likely to be widespread and common with no ecological preference. The phenology chart uses all data for the two Daggers. Two-brood cycles are evident, the main univoltine cycle in July plus a partial bivoltine cycle in May and in August. The national norm is for a single brood in northern Britain and a double brood in the south. An extreme aberration was found at Lodmoor by C Day on 28 June 1932.
