Lennon (1863) makes no mention of it for Dumfriesshire. Gordon (1919) stated it as abundant at Corsemalzie (VC74), along woodsides at dusk. Earliest date was 3rd July 1898.
 
Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43. Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn and Castlehill, Dumfries (VC72) and Kirkconnell Flow, Kirkcudbrightshire.
 
During 1974-93 there were four hundred records from all seven Rothamsted stations, proving it to be widespread.
 
From 1992 to 2010 the regular trapped sites at Kirkton, Cally Woods, Mersehead RSPB, Carsfad at Dalry, Kirkcudbright, Durisdeer and Old Torr/Auchencairn area, with the rest from widely scattered sites across the region.
