Trapezonotus arenarius is a bug fromthe Rhyparochromidae family .
features
The bugs are 4.1 to 5.0 millimeters long. The species looks very similar to Trapezonotus dispar and Trapezonotus desertus and is difficult to distinguish from them. A reliable determination is only possible by examining the parameters of the male genitalia. The antennae are completely black in the female, while the basal antennae is red-brown in the male. In the female, all legs are black, while in the male the first pair of legs is red-brown in color. The species occurs in a more common, fully winged (macropter) form and less often in a brachypteric form with reduced wings. The wing membranes are also often well developed in the brachypteran animals and clearly overlap.
distribution and habitat
The species is distributed almost everywhere in the Palearctic and is only absent in Europe in the extreme south and north. In the east the distribution area extends to Central Asia and Siberia. Finds from North America given in the literature are obviously incorrect determinations of T. desertus . In Central Europe, the species is the most common of its genus, although it is more common in the south and east of Germany than in the northwest. In the Alps, they can only be found in the valleys. Find data up to over 2000 meters above sea level apparently also concern T. desertus . The species often occurs in large numbers. It mainly inhabits dry and temperature-favored, sandy habitats, where it is found in open to partially shaded places. It occurs not only on coastal and inland dunes, but also on human-influenced areas, such as B. ruderal areas in urban areas.
Way of life
On hot days, the adults can be found not only on the ground as usual, but also in the herbaceous layer or even on woody trees. The adults hibernate and mate from April. The females then lay their eggs in May and June and the adults of the new generation appear from the end of July. In favorable years a second generation can appear in the south of Germany, whose nymphs can be observed until November.
