History
Gordon (1919) found it abundant among bracken at light in Wigtownshire. On 23rd June 1906 it was swarming in Kennel Wood, Corsemalzie (VC74); he also found a female there on 4th May 1911. Earliest date was 1st March 1906.
 
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.
 
At Irvine House Lodge, Auchenrivock (VC72), there was a series of records trapped in 1974. Then, during 1975-89 there were 130 records from all seven of the Rothamsted stations proving it to be a widespread species.
 
Regular trapping at Bargaly Lodge, Cally Woods, Carsfad near Dalry and Kirriereoch during 1993 to 2010 accounted for most of the records, all in Kirkcudbrightshire, with a few from Torrs Warren (VC74) and Grey Mare's Tail NTS (VC72) and singles elswhere, being quite scarce in these latter vice-counties.
