History
Somerville (1858) while on a visit to the Moffat area in August of that year had found the larvae on nettle. Lennon (1863) had only found it near Dalskairth (VC73). R. S. Gordon (1913) had found it common on various garden flowers at dusk during June around Corsemalzie (VC74). Earliest date was 1st June 1899.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (VC72). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet during his stay in 1942-43.
 
During 1974-93 all seven Rothamsted stations recorded 170 records between them.
 
From 1993 to 2010 the regular trapped sites at Kirkton, Durisdeer, Cally Woods, Kirkland, Old Torr, Kirkcudbright, Carsfad at Dalry and Mersehead RSPB provided most of the 450 records during this period, with the others from widely scattered sites across the region.

Common Nettle.
