Scolopostethus cf. thomsoni
Family: Lygaeidae

A difficult genus including some common species; all have one large and several small spines on the underside of the front femur. The sides of the pronotum have a large and obvious pale spot just behind the middle.

S. thomsoni
is almost always brachypterous, with a few scattered hairs on the forewings and the antennal pattern, although not absolutely reliable, is useful. Usually, the apex of the 2nd antennal segment is dark, as are the 3rd and 4th segments.

Abundant in a variety of habitats, often associated with nettles. It occurs throughout the UK, but is less common in upland areas.

Compare: S. affinis, S. decoratus
