Trapezonotus desertus is a bug fromthe Rhyparochromidae family .

features

The bugs are 3.7 to 4.7 millimeters long. The species looks very similar to Trapezonotus arenarius and Trapezonotus dispar and is difficult to distinguish from them. A reliable determination is only possible by examining the parameters of the male genitalia. The rails ( tibia ) of the middle legs are often pale in T. desertus , especially in males. There are often brachyptere individuals with shortened wings, but there are also macroptere, with fully developed wings. In the former, the wing membranes overlap a little.

distribution and habitat

The species is widespread in the Palearctic and is mainly boreomontane in Europe. They can be found with small gaps in the center of Europe from the mountains of the northern Mediterranean to Scandinavia. In the east, it spreads across Siberia and Central Asia to Korea. The species is also common in North America. In Germany you can find them in the northwest and with gaps again in the Alps and their foothills. You can find it there from 1300 to well over 2000 meters above sea level, but where it is not common. The species colonizes open heather stocks on sandy and boggy soils, but also partially shaded areas in sparse pine forests. It is also usually found in the mountainous areas on common heather and is well adapted to the high altitudes.

Way of life

The species is so far the only type of bug in Europe in which parasitism by the great fan wing (Strepsiptera) has been documented. Mating and oviposition take place from April, rarely in March. Fertilized females can be found until the end of June; the new generation of adults appear from mid-July. The species evidently only trains one generation per year.
