Davey, P., 2009: A local species restricted to southern Britain, the larva feeding on oak (Quercus spp.). In Dorset, the only site where this species was found historically was Bere Wood, a site that used to contain many acres of old oak tree habitat, before the oaks were replaced with conifers and larch (Larix spp.) in the 1960s. However, old oak woodland in the northern half of the county has yielded singletons in recent years, indicating the presence of colonies. It is not known whether the species is increasing its range of late: Powerstock Common, Piddles Wood, Holt Wood, Chase Woods, Castle Hill Woods. Managing a varied age structure of oak trees at Powerstock Common, Piddles Wood, Holt Wood, Chase Woods and Castle Hill Woods could be beneficial to maintaining this species at these sites.

Care is needed to identify this species correctly as it resembles the Pale Oak Beauty1944. Diagnostics include: presence of a dark patch close to the apex on the underside of the forewing upon which there is a pale mark.
