The black and white ground bug ( Scolopostethus pictus ) is a bug from the Rhyparochromidae family .

features

The bugs are 3.9 to 4.8 millimeters long. As with all species of the genus, the pronotum has a light spot in the middle of the side margin. The membrane on the forewings is colored in a relatively high-contrast. The thighs ( femora ) of the front legs are extremely thickened, the rear legs are very long. The antennae are more than half the length of the body. In contrast to the other species of the genus, only macroptere (fully winged) adults occur.

distribution and habitat

The species is distributed in Europe from the Mediterranean to the south of Scandinavia and is also found on the British Isles. In the east the distribution extends to the west of Siberia and across Asia Minor to the Caucasus . The species is widespread in Central Europe, but is not frequent and partly not proven regionally. It colonizes various habitats, especially those with more humid areas and at the edge of watercourses and apparently requires the vegetation of woody plants such as alder , willow ( Salix ) and oak ( Quercus ), among which most of the finds are documented in the litter and from moss pads . They can also be found in the bank area after spring floods.

Way of life

What the bugs feed on is not yet known. Sucking on seeds is conceivable, but also on fungal hyphae . Sometimes they also climb deciduous and coniferous trees, such as B. Juniper ( Juniperus ) and Arborvitae ( Thuja ). The wintering takes place under loose bark, where you can often z. B. found on plane trees ( Platanus ). Usually one generation develops each year. The adult animals of the new generation appear from late July to August. However, it is possible that an incomplete second generation is formed, whose nymphs then hibernate.
