6 to 7 mm. Stenodema species are elongate grass bugs with a longitudinal furrow between the eyes. The genus is best distinguished by the coarsely and densely pitted pronotum.

Very similar to S. laevigata, but has a much shorter, broader and more rounded appearance. The hairs on the 1st antennal segment are shorter than in other Stenodema species and is no notch on the hind femur.

Grassy areas.

All year. Larvae can be found May-July, the new generation of adults appearing from July onwards.

Overwinters as an adult and mated in the spring, when both sexes turn green, although males are often darker than females. 

Found throughout much of the UK but absent from the south east. It is the commonest Stenodema in upland areas, particularly those dominated by purple moor grass.

Status in Leicestershire and Rutland not known.
