History
Buchanan White of Perth (1895) listed it as occurring in Colvend parish (VC73). Gordon (1913) stated it was local and not uncommon, finding it on White Dyke Low Moor, Corsemalzie, on 9th August 1906. W. S. Brocklehurst informed Gordon that he had taken several at light at Park Place, Glenluce, Wigtownshire in August 1910.
 
Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43. Next was a 1964 record in VC73, followed by RIS data from 1974-93 of 30 records.
 
From 1995-2010 there were under five records recorded annually, except 2002, 2008 and 2009 when there were none, proving what a scarce species this is.
