History
Lennon (1863) stated it was very common in his 'List of Lepidoptera taken near Dumfries.' K. J. Morton of Edinburgh (1900) whilst on a visit in July 1899 to Wigtownshire had found this species in the Monreith area. Gordon (1919) found it to be not uncommon on the moors among the bracken, also found at the coast at Garheugh and Stairhaven (VC74). Earliest date was 2nd July 1911.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn and Tynron (both VC72). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43.
 
During 1964-75 there were only ten records, but from then until 1993 it was recorded regularly at six of the Rothamsted stations.
 
From 1992 to 2010 the regular trapped sites at Kirkton, Durisdeer, Cally Woods and Mersehead RSPB were the popular sites, with other records from widely scattered sites across the region amounting to about 250 records.
