Pachybrachius luridus is a bug fromthe Rhyparochromidae family .

features

The bugs are 4.5 to 5.3 millimeters long. They can be recognized as a representative of the genus Pachybrachius by the pronotum that is typically constricted behind the middle and has no extended margins . One can distinguish the species from the very similar Pachybrachius fracticollis by the long down of the pronotum and by the double row of thorns on the thighs ( femora ) of the front legs. In addition, the pronotum is a little less elongated than the similar species, but rather square. The adults are fully winged (macropter).

distribution and habitat

The species is widespread in Europe, especially in Central and Eastern Europe and is absent in the far north and south. It occurs east of Siberia, China, Japan and Korea and was introduced to Canada by humans. In Germany, the species is mainly found in the northern lowlands, in the east as well as in the Alps and the Alpine foothills. It is rare in the southwest and only occurs locally. In Austria it is only distributed locally and is rare in the Pannonian region. In the Alps, they can be found from low altitudes to around 1300 meters above sea level. In Great Britain it is very rare and only known from a few scattered areas in England and Wales, especially from the New Forest . Unlike the much more common Pachybrachius fracticollis, it is not different humid habitats that are colonized , but predominantly wet moor biotopes . The two types can also occur together.

Way of life

The animals live on sour grass plants (Cyperaceae) such as cotton grasses ( Eriophorum ), turf rushes ( Trichophorum ) and sedges ( Carex ), but mainly on beaked reeds ( Rhynchospora ). The adults can fly and do so especially in spring. Like Pachybrachius fracticollis, the animals mate from May to the beginning of June and become adult after six to eight weeks, from the end of July at the earliest, otherwise from August.
