History
Lennon (1863) under Thera firmaria found it at Tinwald Downs (VC72) but stated it was "not very common." Gordon (1919) found it rather scarce in woods around Corsemalzie (VC74) with specimens being variable. He gave a record for 23rd August 1898 and 1st September 1899, these being the only records for Wigtownshire.
 
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 Castlehill, Dumfries.
 
There was a single record from the Gatehouse of Fleet Rothamsted station in 1979, with a further ten records from Mabie Forest during 1985-92.
 
From 1992 to 2010 seventy records have been recorded from a number of widely scattered sites across the region.
 
Records from VC72 and VC73 are generally for September and October, but with odd ones for July and August.
 
Life cycle
Overwinters as a larva between September and June. Pupates underground.
 
Larval foodplants
Scots Pine.
 
Identification
The adult is quite variable with the forewing generally reddish-brown with a darker central band. The crucial identification point is the inner edge of the cross band which is sharply indented.
 
Habitat
Associated with mature Scots Pine trees, as its common name indicates, in a variety of habitats, but is generally absent from extensive conifer plantations.
 
Recorders' notes
Some records from the past have probably misidentified, so great care is needed in separating the Thera species to achieve a truer picture.
