History
Lennon (1863) stated that it was common and that it had occurred at the Crichton Institution, Dumfries. Gordon (1919) found it common and generally distributed in Wigtownshire, coming to light and sides of woods at dusk. Earliest date was the 1st May 1906.
 
Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43. Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (all VC72).
 
A handful of records occurred in the 1960s, with a fine series from Irvine House Lodge at Auchenrivock in 1974.
 
During 1974-92 there were 200 records from six of the Rothamsted stations, Caerlaverock not recording it.
 
From 1992 to 2010 there were 270 records of which a good portion were from Cally Woods and Durisdeer, with the rest from widely scattered sites across the region.

This dark form has been recorded twice, both from Kirkland (VC72) during late May 2012.
