Davey, P., 2009: A species restricted to southern England, the larva feeding on elm (Ulmus spp.). In Dorset, the moth is very local and colonises thick hedgerow elm on chalky soil where it is usually at low density, and is likely to have declined in recent years from both Dutch Elm disease decimating so much elm, and the enthusiastic implementation of county council policy to precision-strim hundreds of miles of the county’s hedgerows some of which contains elm. Localities producing multiple light trap records include: Puddletown, Shapwick and Gaunts Common. Singletons have been trapped at Folke, Old Harry, Boys Wood, Castle Hill Wood and at Hurn.
