Stenodema holsata
Family: Miridae

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.

S. holsata is similar to
S. laevigata, but has a much shorter and broader appearance, superficially resembling Acertropis gimmerthalii. The hairs on the 1st antennal segment are shorter than in other Stenodema species.

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

Overwintering as an adult and mating in the spring, when both sexes
turn greenalthough males are often darker than females. Larvae can be found May-July, the new generation of adults appearing from July onwards.
