features

The bugs are 6.7 to 8.2 millimeters long. Its head is longer than the first part of the antennae , the fourth part is thickened like a club. The pronotum is structured point-like. The abdomen is striped light and dark on the sides (on the connexivia ). In Central Europe the species is unmistakable.

distribution and habitat

The species is distributed in the Mediterranean and occurs in the east as far as the Caspian region. It occurs increasingly more northerly and has meanwhile also spread to Germany, Austria and Hungary. They are only found locally in Central Europe, but in all habitats that are favorable to them. The northern spread of the species was probably caused by ornamental plants.

Way of life

Especially in the lowlands, the animals only sit on very sunny host plants and sometimes appear there in large numbers. In the Mediterranean area you can find them on junipers ( Juniperus ) and cypresses ( Cupressus ), in the north also on all other cypress plants (Cupressaceae), e.g. B. False cypresses ( Chamaecyparis ) and arborvitae ( Thuja ). The animals overwinter as imago , only rarely as nymphs . Mating takes place from May, the females then lay their eggs until summer. The adults of the new generation appear from late July to early August. In spring one can observe dispersion flights of the species.
