Anthocoris nemorum is a bug fromthe flower bug family (Anthocoridae).
features
The bugs are 3.5 to 4.4 millimeters long. The species of the genus Anthocoris are sometimes very difficult to determine. The hemielytres of Anthocoris nemorum are completely shiny and the pronotum is completely black. The legs are predominantly orange-brown and have variable small dark spots near the tip of the thighs ( femora ), especially the hind legs. The antennae on the second and third segments are predominantly pale, with a dark tip. The first and fourth segments are dark. The two dark spots on the hemielytras are typically hourglass-shaped.
distribution and habitat
The species is distributed throughout Europe and occurs in the east to the Caucasus, Siberia and via Central Asia to China. It is widespread and common in Central Europe. It is one of the most common types of bedbugs. In the Alps you can find them up to about 2000 meters above sea level. In the UK, the species is widespread and common. It is more common here than Anthocoris nemoralis . In particular, moderately moist, open to partially shaded habitats are populated.
Way of life
The animals live both in the herb layer, for example on the great nettle ( Urtica dioica ), and on woody plants, including fruit trees. The predatory bugs feed on various arthropods such as aphids , leaf fleas or spider mites and their pre-imaginal stages, but also on honeydew, pollen and plant saps. Exceptionally, they can sting humans, but they probably only do so when looking for water. The species is considered a beneficial insect in fruit growing. They don't have an ectoparasitic way of life. The overwintering takes place as an imago in various dry places, such as under loose bark or bark scales, in the loose soil litter or in grass groves. At higher temperatures, they can also become active in winter. Mating occurs in autumn and most males do not survive winter. The ovaries of the females only develop after wintering, so that the eggs are not laid between April and June. They pierce a total of around 200 eggs into the epidermis of the young leaves of woody plants and herbaceous plants. This is done near the edge of the leaf. In Central Europe there are two generations per year, the second occurs from June, the wintering first generation appears from September. You can find the adults all year round.
