Lennon (1863) had stated that it was not common, but that it had occurred at Terregles (VC72). Gordon (1913) stated that in Barrett’s British Lepidoptera, it is recorded as occurring in the extreme south-west of Scotland, but obviously he was unaware of any records.

At the Gatehouse of Fleet Rothamsted station two were trapped, one in Mid-June and one in mid-July, both 1979.

Singles were caught at Cally Woods during 1997-99, with two trapped in June, 2000. One was trapped in Rainton Glen at the Cream o’ Galloway on 19th May 2004.
