History
Lennon (1863) stated that it was not very common, but that it had occurred at Terregles (VC72). Gordon (1919) found it common at light at Corsemalzie and Alticry (VC74), with 25 caught between 9th and 10th October 1910. Earliest date was 9th October 1910. William Evans received specimens from Mowat, the Killantringan lighthouse keeper during 1914 and 1915 to aid his insect migration studies.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (all VC72). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43.
During 1974-90 all seven Rothamsted stations recorded it in varying numbers. Then, from 1992 to 2010 with regular trapping, Kirkton and Durisdeer (VC72), Cally Woods and Carsfad near Dalry (VC73) accounted for most of the records, with a small scattering elsewhere in the latter VCs. Forest Moor, Wigtownshire, in 2006, was the only site for that VC during that period.
