History
Lennon (1863) stated that it was not common, but that it had occurred at Kirkconnell (VC73). Gordon (1913) had found it common on moors around Corsemalzie, Wigtownshire, especially on the heather blossom in August. Earliest date was 16th August 1910. William Evans had received specimens from Mowat, the Killantringan (VC74) lighthouse keeper as part of his migration study of insects.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn and Castlehill, Dumfries (all VC72). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43.
 
During 1974-93 it was regularly recorded at five of the seven Rothamsted stations, Newton Stewart and Caerlaverock missing out. From 1990 to 2010 it has still been recorded regularly with personal trapping equipment.
