Davey, P., 2009: A common species across southern Britain, more local elsewhere, the larva feeding on hawthorn (Crateagus spp.), blackthorn (Prunus spp.), apple (Malus spp) and aspen (Populus tremens). In Dorset, the moth is most frequent amongst hawthorn and blackthorn, and least common on open heathland. The national norm is for a single brood in May and June, however, the prolonged flight period of three months in Dorset is unlikely to be a single emergence, and two broods are suspected. The peak in early July may indicate adults from both broods on the wing at the same time. The following three moths were trapped at light on the coast during immigration events and are suspected immigrants from regions of the Continent that support an autumn brood: Walditch, on 29 October 2006 (M Parsons), West Bexington, on 2 September 2004, 19 September 2005 (R Eden), Durlston, on 23 October 1996, 10 September 1999 (P Davey).
