Scolopostethus thomsoni is a bug fromthe Rhyparochromidae family .
features
The bugs are 3.4 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 thomsoni is almost always Brachypter, so it has shortened wings. The species has occasional hairs on the forewings. The sampling of the feelers can also help with the determination, but is not always reliable. Usually the tip of the second segment is black, as is the entire third and fourth segment.
distribution and habitat
The species is that of the genus Scolopostethus , which is most widespread and is most common in Central Europe. It is distributed in the Holarctic and can be found in Europe from the Mediterranean region to the far north. To the east, the distribution area extends over Siberia and Central Asia to Japan. It is also found in North America. In Central Europe, the species is widespread and common and rises in the Alps to well over 1000 meters above sea level. The species occurs wherever the great nettle ( Urtica dioica ) occurs, so it occurs in almost all dry to moist habitats, regardless of the nature of the soil.
Way of life
The animals suckle polyphagous on the seeds of many herbaceous plants and woody plants, but are similar and even more like Scolopostethus affinis to nettles ( Urtica ) and in particular the greater nettle. The nymphs need the seeds of these plants for optimal development and later an appropriate egg production. Accordingly, the nymphs and adults are often found on these plants while sucking on the seeds. Like most other species of the genus, this species also laid eggs in May and the adult animals of the new generation appear from late July to early August. Under favorable conditions, however, an incomplete second generation can be formed per year, of which the nymphs overwinter in the third to fifth instar. Eggs can be laid not only on the ground, but also around the inflorescences of the nettles.
