Teratocoris antennatus is a species of bug from the family of soft bugs (Miridae).

features

The bugs grow to be 3.3 to 5.7 millimeters long, with the females being slightly larger than the males. The species of the genus Teratocoris have a transverse pit between the compound eyes . The identification of species within this genus is difficult, especially in the case of females. In Teratocoris antennatus , the first part of the antennae is usually predominantly reddish and only sparsely covered with short, fine, inconspicuous hairs. The pronotum is deeply concave in the middle. The basic color of the bugs varies from orange-brown to green. Males can have a strong black pattern. In both the females and the males, the wings are often more or less shortened. Females with fully developed (macropter) wings can rarely be seen.

Occurrence and habitat

The species occurs almost all over Europe, the western Mediterranean area to North Africa and east to Siberia. The species occurs everywhere in Germany and Austria, but has only been found sporadically and is not common. Presumably it has not yet been discovered in many places. Dense reeds and sedge stands are settled on the edges of fresh and brackish water and in bogs with vegetation of sweet grass, sour grass and rushes.

Way of life

Teratocoris antennatus lives mainly on reeds ( Phragmites australis ) and cane grass ( Phalaris arundinacea ), but in the inhabited habitats there are usually also swaths ( Glyceria ), ledges ( Scirpus ), rushes ( Juncus ) and sedges ( Carex ). Both the nymphs and the adults rarely stay on top of the plants. The males in particular prefer to live near the ground, which can sometimes be flooded. The bugs suckle on the vegetative parts of their host plants as well as on the reproductive organs. In addition, they also prey on aphids , the larvae of cicadas , the caterpillars of small butterflies and other insects. You can see adults in northern Germany from mid-July through October or November. The overwintering takes place in all probability as an egg. In the south of Germany you can see the adults from late May to August and September.
