Stygnocoris rusticus is a bug fromthe Rhyparochromidae family .
features
The bugs are 3.1 to 4.4 millimeters long, making them the largest species of their genus in Central Europe. Representatives of the genus Stygnocoris can be recognized by the fine hairs on the pronotum and the hemielytras . The pronotum is completely punctured and the thighs ( femora ) of the front legs do not have spurs. Stygnocoris rusticus has a uniform black colored pronotum. Its dorsal side is dull and has short fuzz. The animals usually have reduced (brachyptere) wings, but there are also those with fully developed (macropter) wings, especially females.
distribution and habitat
The species is distributed in Europe with the exception of the far north and the extreme south and east to Central Asia. The species was introduced into North America by humans. It is widespread in Central Europe and common almost everywhere. It rises well above 1000 meters above sea level in the Alps, and can also be found in the low mountain ranges. It is widespread in the UK but only occurs locally. Various open to partially shaded, moist to dry and warm habitats are settled. They can be found on coasts with salty soils, banks of fresh water and moors, as well as in sandy and limestone grasslands and not infrequently on ruderal areas and cultivated land with a dense layer of herbs.
Way of life
The animals live on the ground. The adults suckle on fallen seeds, but also on immature seeds on the plants. They are polyphagous and apparently not bound to any particular food plants. The females lay their eggs in the stems of herbaceous plants or in dead plant material on the ground. The development takes place in the same way as with Stygnocoris sabulosus : Mating does not take place until August and September, the eggs are laid from September through January. The hibernation takes place in the egg, only single adults, especially females, survive the winter. The nymphs hatch from May .
