Lennon (1863) stated that it was not common, but that it had occurred at Dalskairth (VC73). Gordon (1913) found it generally distributed in Wigtownshire, coming to light and sugar during early June. Earliest date was 31st May 1911.

Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (all VC72).

During 1974-92 six of the seven Rothamsted stations recorded it regularly, Caerlaverock not finding the species.

Durisdeer (VC72), Carsfad near Dalry and the Wood of Cree area (both VC73) were regular sites where it was trapped during 1992-2010, but only six records came from Wigtownshire in that period.
