This species has been recorded widely south-east of a line between Bristol and York, with isolated records also in Wales, south-west England and northern Scotland. There appears to have been a reduction in observations in recent years (Musgrove, 2023).

Legs are black with white on the trochanters, fore and middle femora apices and tibiae. The apices of the fore and mid tibiae and all tarsi are reddish brown.
