History
The first notice we have is when Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43. The lateness of the first record is not surprising as it only became a full species during the 1920s.
 
The next five records all came from mainly coastal Wigtownshire sites during 1987-98, at St Ninian's Cave, Torrs Warren, Mull of Galloway, Challochglass Moor and Fell of Carleton.
 
A second record for Kirkcudbrightshire came in 2010 on Barcloy Hill.

None of these records were fully authenticated, and due to the difficulty of separating this species from July Belle it was questioned whether this species existed in Dumfries and Galloway. However, one caught on 21 July 2015 at Drummore was verified by genitalia dissection, finally confirming beyond doubt the presence of this species in the region.
 
Life cycle
One generation. Overwinters as a larva during August to March.
 
Larval foodplants
Gorse, Broom, Petty Whin and Dyer's Greenwood.
 
Identification
The position of the discal spot on the forewing is the key.
 
Habitat
The larval foodplants tend to be found most frequently in coastal or lowland habitats.
 
Recorders' notes
Due to the difficulty of separating this species from July Belle, a voucher specimen or good quality photo is required for record acceptance.
