Anthocoris sarothamni is a bug from the family of flower bugs (Anthocoridae).

features

The bugs are 3.1 to 3.8 millimeters long. The species of the genus Anthocoris are sometimes very difficult to determine. Anthocoris sarothamni, however, is one of the relatively easy to identify species, as it is very dark in color compared to the other species. The thighs ( femora ) of the middle and rear legs are characteristically very dark, as are the antennae , each segment being pale in color directly at the extreme tip. The latter feature can also be used to identify the nymphs . The splints ( tibia ) also have a relatively large amount of red in their coloration. The hemielytres are completely shiny, only a matt band runs along the seam between the corium and clavius.

distribution and habitat

The species is European and especially widespread here in the west. It occurs from the British Isles across western and central Europe to the western Mediterranean and in the east to Poland and the Balkans. It is presumably widespread in Germany, but only sporadically proven and is more common in the west than in the east, but rare everywhere. It does not occur in Austria. The species is widespread in Great Britain.

Way of life

The animals live in Central Europe at Broom ( Cytisus scoparius ), in the Mediterranean they are also found on broom ( Genista ), spiny broom ( Calycotome ) and Daphne ( Daphne ). They mainly feed on leaf fleas and their larvae, especially the genus Arytaina , but also on aphids . In April and May, the females prick their eggs under the epidermis of the leaves of the host plants. Occasionally they do this in the stems as well. The adult animals of the new generation appear from June. In Germany, these then go into diapause and do not develop a second generation, presumably because the leaf fleas on broom are then missing as a food source.
