Lennon (1863) stated it was very common in his 'List of Lepidoptera taken near Dumfries.' Gordon (1919) found it scarce on tree trunks and after beating at Corsemalzie (VC74) during July.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn (VC72). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43. From 1975-79 it was recorded regularly at the Gatehouse of Fleet Rothamsted station and also at the Waterside Mains (VC72) station during 1980-82.
 
Between 1990-2010 it was only found at Lochmaben and Closeburn in Dumfriesshire; The Forest and High Mark in Wigtownshire; with Kirkcudbrightshire producing most from sites at Bargaly Lodge, Carsfad, Loch Kindar, Maggot Hill, Hannaston Wood, Cally Woods and Caldons Wood, Glentrool.
