Davey, P., 2009: A species found in southern Britain, the larva feeding on oak (Quercus spp.), and abroad also on blackthorn (Prunus spp.), sallow (Salix spp.), elm (Ulmus spp.) and poplar (Populus spp.). The moth hibernates overwinter and pairs during the spring. It is attracted to light traps and is occasionally found at ivy blossom in the autumn or at sallow blossom during the spring. In Dorset, the moth is at low density in deciduous woodland with highest numbers from old oak woods. However, records from districts where oak is absent suggests an alternative food source is used. For example, the moth has been observed regularly at West Bexington and at Shapwick where blackthorn is frequent, and this may be the host foodplant in these localities. The adult occasionally emerges from hibernation during mid-winter mild spells.
