Davey, P., 2009: A local species, the larva feeding on ash (Fraxinus excelsior) in mainland Britain, and on sea buckthorn (Hippophae rhamnoides) along south-east and eastern coasts of England. The species has also been found on tamarisk (Tamarix gallica) in neighbouring Hampshire (Goater, Norris, 2001). Abroad, the species is polyphagous, with blackthorn (Prunus spinosa) and dog-rose (Rosa canina) mentioned as foodplants. In Dorset, this distinctive elongated-winged moth is rare, and the sporadic nature of the few records we have, makes it difficult to assign a resident status to the species, particularly as the majority of the records are from the coastal belt where dispersal is suspected. The few examples found inland and not linked to immigration originate from the central chalk downs of Dorset: Chilfrome, on 19 July 2003 (S Philp), Puddletown, 19 June 2002 (H Wood Homer), Iwerne Minster, on 18 June 1967 (H Moore), Hambledon Hill, 18 July 1989 (Miss M Brooks).
The following light trap records occurred in mainly coastal localities in easterly airflows, hinting at medium range dispersal from colonies in south-east coastal counties or displacement from the coasts of France or Belgium - see wind rose (chart 1): West Bexington, 20 May 1998, 30 July 2002, 17 August 2002, 9 and 10 July 2003, 6 August 2003, 4 June 2004, 11 and 14 July 2005, 3 July 2006 (R Eden), Weymouth, on 31 May 1997, 2 July 2006 (Dr P Sterling), Portland, on 17 August 1996 (M Cade), Grove, on 8 August 1998 (D Walbridge), Gaunts Common, on 16 May 1992 (P Davey), Scar Bank, on 9 August 1933, 30 August 1948 (A Russell).
