Davey, P., 2009: A widespread species in southern Britain, and absent in the north, the larva feeding on oak (Quercus spp.). In Dorset, the moth is local and usually at low density in woodland and parkland where there are good numbers of mature oak trees; populations are greatest in old oak woods. Elsewhere and particularly in open habitat, it is seldom encountered.
