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.

Recording method

Easily disturbed from pines during the day and comes to light occasionally in large numbers.

Life cycle

Overwinters as a larva between September and June. Pupates underground.

Larval foodplants

Scots Pine.

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

History 1860-2010

First recorded for Dumfries and Galloway for VC72  in 1862 at Tinwald Downs, Dumfries by Lennon who stated it was ‘not very common’, for VC74 in 1898 at Corsemalzie  by Gordon who found it ‘rather scarce in woods’ and for VC74 in 1942 near Gatehouse of Fleet by Russell.

Some records from the past have probably been misidentified, so great care is needed in separating the Thera species to achieve a truer picture.
