Davey, P., 2009: A species restricted to England and Wales, the larva feeding on buckthorn (Rhamnus cathartica). In Dorset, the moth is local and at low density, and occupies similar habitats to the Brown Scallop1791. This species is fairly regularly recorded from just one site on sandy soil, Hurn. Here the species is associated with alder buckthorn (Frangula alnus) - see also Brown Scallop1791.
