History

Somerville (1858) whilst on a visit to the Moffat area had found it was attracted to sugar in August of that year. Gordon (1913) stated that several were taken at sugar in a wood near Loch Elrig, Mochrum (VC74) by J. Garraway. William Evans (1916) received a male from Little Ross Lighthouse sometime during 1915 to aid his insect migration studies.

Sir Arthur Duncan (1909-84) had noted it at Closeburn, Tynron and Dumfries (all VC72) during his lifetime, while Russell (1944) had found it near Gatehouse of Fleet during 1942-43. Pelham-Clinton also recorded it during the early 1960s with records from Palnackie and Rockcliffe (VC73). The only other record in the 60s was from 1969 at Clatteringshaws Loch.

From then on it appeared regularly at all seven of the Rothamsted stations thus greatly adding to our knowledge of the species. There have been many nights with counts of 14, 15, 16, found in a single light trap at the regular trapped sites of Kirkton, Durisdeer, Cally Woods and Mersehead RSPB.
