Coranus subapterus is a species of bug from the family of predatory bugs (Reduviidae).

features

The bugs are 9.0 to 12.5 millimeters long. Their body is brownish-gray to ash-gray in color and hairy gray. The head has a yellowish vertical line and is slim, conical behind the compound eyes . The second part of the antennae is imperceptibly shorter than the third. The first link is very long. The scutellum has a pointed, yellowish, erect thorn behind. The animals have predominantly more or less strongly or even flaky shortened wings. There are also individuals with fully developed wings (macropter), although it is not uncommon for animals to be found that are macropter on one side, i.e. have correspondingly shortened wings on the other side.

Occurrence and habitat

The species is distributed in Europe and east to Central Asia and the west of Siberia. It is widespread in Germany and Austria and also occurs in the higher elevations of the low mountain ranges and the Alps. It is not uncommon. Dry, warm, open habitats are settled without any preference in terms of soil quality. They can be found in sandy, vegetation-free and also in rocky or coarse gravel habitats, as well as on dried-out bog soils or in places influenced by salt. The species that is barely able to spread, however, avoids habitats in which the succession of vegetation progresses rapidly, such as on fallow land or ruderal sites.

Way of life

Coranus subapterus is diurnal and can often be found below the leaf rosettes of mullein ( Verbascum ), adder's heads ( Echium ) and under low-lying branches of field mugwort ( Artemisia campestris ) or in the cushions of thyme ( thymus ). The Imagines hardly climb on the plants up. They and the nymphs hunt various insects, such as ground bugs , but also spiders and harvestmen. Only one generation is trained each year. The eggs overwinter. The nymphs appear from late April / early May and are adult from July. The adults can be observed until October or, rarely, November. The mating season is in August and September.
