History
Found only three times in Dumfriesshire: Dumfries 1977, Glencaple 2008, and Kirkton 2010. Otherwise, one from Mabie Forest in 1977, Gatehouse-of-Fleet in 1979 (RIS data), Mersehead in 1996, Auchencairn, Ross Bay in 2002, and Old Torr on Auchencairn Bay in 2009 and 2010, all Kirkcudbrightshire. In July, 2006, it was trapped on a couple of occasions at Forest Moor, Wigtownshire.
 
Five of the localities are coastal suggesting future colonies from a northerly spread, of which Dumfries & Galloway is the most northerly site in Britain.
 
Life cycle
One generation. Overwinters as a small larva during July to early June, with pupation taking place among the leaves of the foodplant.
 
Larval foodplants
Larvae feed on Hawthorn, Blackthorn and other woody plants.
 
Identification
The pointed forewings with chequered fringes and wavy cross-lines with a single projection on the hindwing are diagnostic.
 
Habitat
Woodland, scrub and hedgerows.
