Davey, P., 2009: A common species in Britain, the larva feeding on a variety of deciduous tree and shrub species. In Dorset, the moth is widespread and frequent. It is common where blackthorn (Prunus spp.) and hawthorn (Crateagus spp.) grow, particularly on chalky soil. It is rare on open heathland. The second brood is twice the size of the first brood.
