Davey, P., 2009: A species occurring across England and Wales, the larva feeding on ash (Fraxinus spp.). In Dorset, the moth is widely distributed across the county wherever ash is found, but it is usually at low density and seldom common. It is found in ash-dominated woods that grow on chalky soil, and in open localities where ash grows in relative isolation.
