History
Buchanan White of Perth (1895) listed it as occurring in Colvend and Southwick parishes (VC73) stating it to be the first Scottish locality. Additional to MOGBI. Gordon (1919) found it abundant among bracken, with hundreds among there at dusk in Kennel Wood, Corsemalzie (VC74) on 13th May 1906. It also came to light. Earliest date was 1st May 1912. 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.
 
During 1974-92 six of the seven Rothamsted stations caught the Brown Silver-lines on a regular basis, with Caerlaverock missing out. From 1993 to 2010 Cally Woods recorded many records; elsewhere it was recorded from many sites in VCs 72 and 73 proving it to be widespread, but with fewer records from Wigtownshire, probably due to lack of recorders.
