Stenodema trispinosa
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, although the three spurs on the hind femora make this species unmistakeable. S. calcarata has two femoral spurs.

Local in south east England and East Anglia, this species is usually found in wetlands, including brackish situations, feeding on various sedges.

This bug overwinters as an adult and emerges in April and the new generation is complete by August.

Compare: S. calcarata,
S. laevigata
