Stenodema calcarata


Length 7-8 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, although the two spurs on the hind femora of Stenodema calcarata make this species unmistakeable. After emerging in the Spring, the females turn green whilst the males remain straw-coloured. Late-instar nymphs have a single femoral spur.
