Anthocoris confusus is a bug fromthe flower bug family (Anthocoridae).
features
The bugs are 3.2 to 3.9 millimeters long. The species of the genus Anthocoris are sometimes very difficult to determine. The hemielytres of Anthocoris confusus are shiny only on the cuneus, the outer part of the embolium along the outer edge and on the apex of the corium. The first antenna segment is dark, the second is largely pale at the base. Compared to Anthocoris nemorum, the hemielytres are relatively dark and also have a slightly different pattern. The differentiation from Anthocoris nemoralis is very difficult. This similar species usually has slightly paler colored thighs ( femora ).
distribution and habitat
The species is widespread in the Palearctic and occurs everywhere in Europe with the exception of the far north and the extreme south. To the east, it spreads to China and Japan. The species was introduced to North America by humans. In Central Europe it is widespread and generally not uncommon. In the UK, the species is widespread and common.
Way of life
The animals live on different deciduous trees and feed on prey on aphids , for example, the family Thelaxidae , more rarely, of psyllids or dust lice . You can find them on willows ( Salix ), beeches ( Fagus ), maples ( Acer ), linden ( Tilia ), oaks ( Quercus ), hawthorns ( Crataegus ), elms ( Ulmus ), poplars ( Populus ) or ash trees ( Fraxinus ) . Most of the males die over the winter, while the mated females overwinter under the loose bark and bark scales of plane trees ( Platanus ), horse chestnuts ( Aesculus ), pears ( Pyrus ) and sycamore maples ( Acer pseudoplatanus ). The ovaries of the females do not mature until spring, which means that the eggs cannot be laid until May. The adult animals of the new generation appear from July. In these, the sexual organs partially mature immediately, so that these animals can develop a second generation before winter, whose adults appear from September. However, the majority overwinter and only reproduce in the next year. Unlike the other species of the genus, the females pierce their eggs deep into the tissue of the plants in leaf veins and stems.
