History
Lennon (1863) stated that it was not common, but that it had occurred at Dalskairth (VC73). 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 on all moors in Wigtownshire, during June.
 
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 1976-93 there were thirty records from these four Rothamsted stations: Newton Stewart, Penningham, Gatehouse of Fleet and most of all Mabie Forest.
 
From 1991 to 2010 the remaining fifty records have all been found at widely scattered heathland or moorland sites across the region, with odd records from gardens adjacent to those habitats.
 
Confirmed across the region in Riley & Prior (2003).
 
Life cycle
Two overlapping generations. Overwinters as a pupa. Larvae are present mid-June to late September.
 
Larval foodplants
Heather flowers.
 
Identification
The lengthy, narrow forewings, with strongly angled cross-lines edged with white on a light and dark marbled forewing appearance should identify it. The adopted posture shown above will also help, but it can rest like most other pugs.
 
Habitat
Heathland and moorland.
