Trigonotylus ruficornis is a species of bug from the family of soft bugs (Miridae).
features
The bugs are 4.0 to 6.5 millimeters long. The species of the genus Trigonotylus have an elongated body with a longitudinal furrow between the compound eyes and a smooth, unpunctured pronotum . The first part of the antennae has short, prickly hairs and is no longer than the head. In Trigonotylus ruficornis and Trigonotylus caelestialium , the first antennae is mostly red and has pale longitudinal stripes. In Trigonotylus ruficornis these are much more diffuse and less contrasted.
Occurrence and habitat
The species is widespread throughout Europe, but occurs mainly in the Mediterranean area. The distribution extends in the south of North Africa east to Asia Minor and at least to the Middle East. It is still unclear where the species is distributed further east in Asia. It has only been clearly differentiated from Trigontylus caelestialium for a few decades , so that older findings cannot be clearly assigned. The species is likely to be found everywhere in Germany, but so far it has only been proven in isolated cases. It is much rarer than Trigontylus caelestialium . Open, dry and warm habitats are populated, such as dunes, limestone and sandy grasslands, where it occasionally occurs together with Trigontylus pulchellus . The species is rarely found in mesophilic areas, where it then occurs together with Trigontylus caelestialium . The species also occurs in salt-influenced habitats near the coast.
Way of life
Trigonotylus ruficornis lives on sweet grasses (Poaceae) and rush plants (Juncaceae). They can be found in sandy, hot and dry places. B. on silver grass ( Corynephorus canescens ) or sand sedge ( Carex arenaria ), in less dry places on wire smut ( Deschampsia flexuosa ) or fescue ( Festuca ). Adults occur over several months from June to October. It could be two generations, but this is still largely unclear.
