Davey, P., 2009: A local species in England, Wales and southern Scotland, the larva feeding on english elm (Ulmus procera) and wych elm (Ulmus glabra). Whilst dutch elm disease continues to plague elm trees across the country, this species remains under threat. In Dorset, there are just three light trap records: Holnest, on 19 July 2000 (J Astley), Puddletown, on 9 September 2007 (H Wood Homer), Higher Hyde, on 7 August 1996 (Dr P Sterling). It is just possible that the Holnest example originated from a small colony as there is plenty of elm in the Blackmore Vale area, but equally it may have dispersed from a colony upwind in Somerset or south-east Wales. Subsequent trapping at Holnest has not yielded any further moths. The Puddletown example also occurred coincident with a light northerly airflow. The first week of August 1996 was dominated by a warm south-easterly airflow flow transporting many immigrant moths to southern England. The Higher Hyde example probably originated from central or northern France.
