Teratocoris antennatus
Family: Miridae

Teratocoris species are mainly green grass bugs which are found in damp or wetland habitats. They have a transverse furrow between the eyes. Species identification is complex and particularly difficult in females.

The 1st antennal segment of T. antennatus is usually mainly reddish and sparsely covered with short, fine inconspicuous hairs. The middle of the pronotum is strongly concave. The ground colour varies from orange-brown to green and males may be extensively marked with black.

Found locally across the UK in marshes and damp habitats, feeding on sea club-rush.

Adult: July-October
Length 3.5-6.0 mm
