The earliest notification of this species is published in Stephens (1829) with the Rev. William Little recording it at Raehills (VC72).
 
K. J. Morton of Edinburgh (1900) whilst on a visit in July 1899 to Wigtownshire had found this species in the Monreith area. Gordon (1919) found it very common and generally diistributed in Wigtownshire. The banded forms being common among fern and bracken. Earliest date was 20th June 1911.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn and Castlehill in Kirkmahoe parish (all VC72). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43.
