History
The earliest notification of this species is published in Stephens (1829) with the Rev. William Little recording it at Raehills (VC72) stating it to be abundant.
 
Somerville (1858) while on a visit to the Moffat area during August had found it in local woods. Lennon (1863) had found it not common, but had found it near Terregles. J. Garraway in April, 1903, had collected several larvae at Alticry Glen, Luce Bay (VC74), which he bred on (Gordon 1919). This is the only Wigtownshire record.
 
It was then not recorded until 1975 when Pelham-Clinton found it at Kirkconnel (VC72) and another was found during 1975-80 at Springfield, Gretna (VC72). It was then found to be resident in Mabie Forest (Rothamsted data) from the 1980s onwards.
 
During 1992 to 2010 it had been found at Bargaly Lodge, Knockman Wood, Buchan Burn and Kirkconnell Flow (VC73), and Goukstane Burn, Glenmaid Moor, Glenwhargen Craig, Grey Mare's Tail, Moffat and the Carrifran Valley (VC72).
