Mecomma ambulans is a type of bug from the family of soft bugs (Miridae).

features

The bugs are 4.4 to 4.8 millimeters (males) or 2.4 to 3.5 millimeters (females). The species of the genus Mecomma show a sexual dimorphism . The males are fully winged (macropter), the females usually have shortened (brachyptere) wings. One can distinguish the males from those of Mecomma dispar by the completely black antennae and by the pronotum , which is significantly wider than the head. The females have dark hemielytras . The first antenna segment is dark, the second is not thickened like a club. The dark head distinguishes them from the females of Orthonotus rufifrons .

Occurrence and habitat

The species is distributed from Lapland in the north to North Africa in the south and east over Siberia to China and Korea. In Germany it is widespread and as a rule frequent, especially in the montane areas it occurs with a large number of individuals. In the North German lowlands it is rare in places. In Austria, with the exception of the Pannonian region, it is widespread in the east and is common in some places. The herb layer is colonized close to the ground by moist to wet habitats, often in sparse woody stands, but the species also occurs in open habitats or in dense coniferous forests.

Way of life

It is not known how the bedbugs feed. The nymphs also feed predatory. the adult bugs often climb on various plants, such as ferns or grasses, but do not necessarily suck on them. It is not known whether the species feeds on those plants on which it also occurs together with Mecomma ambulans . These are quail wheat ( Melampyrum ), hollow tooth ( Galeopsis ), nettles ( Urtica ), violets ( Viola ) and various sweet grasses (Poaceae), rush family (Juncaceae) and sour grass family (Cyperaceae). The adult bugs appear from the end of June and are most common in July, where mating and oviposition also take place. The bugs die in August and September. The females pierce their eggs in the lower areas of sweet and sour grasses, among other places.
