Scolopostethus affinis is a bug fromthe Rhyparochromidae family .
features
The bugs are 3.1 to 4.0 millimeters long. The species of the genus Scolopostethus are difficult to determine. They have one large and several small thorns on the underside of the thighs ( femora ) of the front legs. They also have a large pale spot in the middle of the margin of the pronotum . Scolopostethus affinis can be determined from the short wing membrane, which is three times wider than it is long, and the characteristics of its antennae . The first two limbs are pale, the third and fourth are dark, the third limb is usually pale at the base. Occasionally there are also fully winged (macroptere) individuals in which the pronotum is narrower than usual.
distribution and habitat
The species is distributed in Europe from the northern Mediterranean to the south of Scandinavia and the British Isles. In the east, the distribution extends to Western Siberia and via Asia Minor into the Caspian region. It is common everywhere in Central Europe. The species is found in nutrient-rich locations with no preference for soil moisture, both in sunny and shady places.
Way of life
The animals suckle on seeds lying on the ground as well as on immature seeds of various herbaceous plants. They only seldom suckle on trees. They are mainly found on nettles ( Urtica ). The development is different for each individual. As a rule, you can find adults all year round, nymphs are mainly found in summer, but also during the winter. In favorable years it is possible that a partial or complete second generation will be trained. The eggs are laid in May and June. The animals overwinter in the litter and under dead wood or loose bark. It is possible that the animals are transported by the water over great distances during flooding in alluvial forests.
