Vulnerable (proposed as a future Red Data Book species) in parts of south-western Britain, where recorded on just a few occasions. The first was at Axminster, Devon in June 1986; in 2006, two were found in Wetmoor, Gloucestershire; one was in Lineover Wood, Cheltenham, Gloucestershire in June 2009. It would seem that there must be a colony at Wetmoor, which is part of the enormous Lower Woods GWT Reserve, and that this is a previously overlooked species. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan 10-12 mm. Voucher specimen should be retained for confirmation of identification. Larva feeds on Ash and Elm.
