Thera britannica

(Turner H J, 1925) 1769 / 70.079

General comments:
Widespread resident.

Older literature refers to this species as T. variata subspecies brittanica. A widespread and numerically common species it can be confused easily with the various colour forms of several other Thera species - the shape/angle of the inner edge of the median fascia provides a critical feature.

Recorded in 35 (85%) of 41 10k Squares.
First Recorded in 1940.
Last Recorded in 2023.
