Psallus haematodes ( Syn .: Psallus roseus Fabricius , 1777, Psallus alni Fabricius , 1794) is a type of bug from the family of soft bugs (Miridae).
features
The bugs are 3.0 to 3.8 millimeters long. The genus Psallus includes small, often red, gray or dark brown speckled bugs, in which the pronotum and the hemielytres are covered with pale, scale-like hairs and in which the thorns of the rails ( tibia ) arise from black points. The species of the genus can often only be differentiated with difficulty or not at all on the basis of external characteristics. Most of the time, however, the species can be narrowed down based on the host plant. Psallus haematodes is one of the few species of the genus Psallus that are relatively easy to identify . The Cuneus is always completely white and its basic color is pale and mottled with red or reddish brown. Occasionally there are animals whose top is completely pink.
Occurrence and habitat
The species occurs almost everywhere in Europe, but occurs only in the north of the Mediterranean. To the east the distribution area extends to Siberia and the Caspian region. It was introduced into North America by humans. It occurs everywhere in Germany and Austria and is common. Open, sunny, but also shady places on the edge of water bodies and in moors and also in dry habitats are populated.
Way of life
Psallus haematodes lives on broad-leaved willows ( Salix ), such as sal willow ( Salix caprea ), ear willow ( Salix aurita ) or ash willow ( Salix cinerea ), but also occurs rarely on creeping willow ( Salix repens ) narrow-leaved species such as basket willow ( Salix viminalis ). The adults appear relatively late from early / mid-July to September / early October.
