Davey, P., 2009: A local montaine and rocky coast species restricted to northern and western districts of Britain plus a few localities along the south coast of England, the larva feeding on various grasses and herbaceous plants including harebell (Campanula rotundifolia), saxifrage (Saxifraga spp.) and stonecrop (Sedum spp.). In Dorset, the moth is confined to the Purbeck coast and Portland where it is rarely recorded. It has a protracted flight period, and may be seen at any time between mid-June and early-September. Its habit of dashing wildly about on sunny days in the middle of the afternoon seems not to have been observed in the county. It is fond of visiting valerian flowers at night. |
