Davey, P., 2009: A species confined to the coastal counties of southern England and south Wales, the larva feeding nocturnally on lichens growing on rocks and walls, including Diploicia canescens. In Dorset, the moth is frequent on rocky or pebbly coasts, but rare inland on walls constructed from limestone or brick walls with lime pointing. "Sometimes fairly common, but the class of old stone wall suitable to this species is decreasing, but it will take to old cool brick walls and to old hardwood posts. It must, however, be in positions where atmospheric moisture is available, not necessarily rain. Common on the walls of an old stone house at Longfleet at Poole. These walls were made of Lyme Regis lias, and were overgrown with lichen" (W Parkinson Curtis manuscript).
