Plagiognathus arbustorum is a species of insects in the family Miridae, the plant bugs.

Distribution

This very common species is present in the Nearctic realm, in most of Europe and east to Siberia and Central Asia.

Habitat

These mirids inhabit high-altitude herbaceous habitat, ruderal areas and even salt spots. In the Alps they can be found up to over 2000 meters above sea level.

Description

Adults of Plagiognathus arbustorum can reach a length of 3.6–4.5 millimetres (0.14–0.18 in). These small mirids show a rather variable color, ranging from almost black to pale olive-green. Usually the head and the pronotum, the 1st and 2nd antennal segments and the margins of the hind femora are wholly dark. Forewings and pronotum are covered in dark hairs. The nymphs are green, with a black drawing on the legs.

Biology

Adults of these mirids can be found from July to October. They are polyphagous, usually feeding on many different herbaceous plants, but especially on Urticaceae, Asteraceae, Lamiaceae, Fabaceae, Rosaceae and Apiaceae species.

Both adults and the nymphs prefer to suck on the buds, on flowers and immature fruits of their host plants. They feed occasionally on aphids and honeydew.
