Berytinus hirticornis is a bug from the family of stilt bugs (Berytidae).

features

The bugs are 7.8 to 10.6 millimeters long, making them the largest representatives of their genus in Central Europe. Characteristic for representatives of the genus Berytinus they have a short second antennae , which is shorter than the club-shaped thickening at the end of the first antennae. They also have short thighs ( femora ) on the hind legs that do not reach the tip of the corium of the hemielytrae . In Berytinus hirticornis the first antennae has long, upright hair that is longer than the segment is thick. The lobe of the first antennae and the thighs are pale in color.

distribution and habitat

The species is distributed from North Africa across the Mediterranean to northern Central Europe and southern Great Britain and east across Southeastern Europe and Asia Minor to Central Asia. The species is rare in Central Europe, only locally distributed and often only documented by historical evidence. Evidence is missing in the north-west German lowlands, southern Bavaria and Baden-Württemberg. In Germany, the species is most frequently documented from the Middle Rhine region and eastern Germany. In Great Britain, the species was previously only found in Devon , but it is now also found in other parts of the country and is more common in places in the southwest. Dry and warm areas with sandy and limestone soils are settled.

Way of life

The animals live on the ground in the herbaceous layer and feed on sweet grasses (Poaceae), such as agropyrum and ball grasses ( Dactylis ). The nymphs and adults climb on the plants and suckle on the stalks and leaves. The adults overwinter in cushions of moss, under plant rosettes or in the dry litter . The females lay the eggs individually on the leaves of the food plants in May and June. The adults of the new generation appear from July. In Europe, one generation is trained every year.
