features

The bugs are 3.2 to 3.9 millimeters long. You can recognize the completely shiny hemielytres and the strong brown color (including the hemielytres) by the front collar and the bent back sides of the pronotum . The middle part of the second antenna element is lighter than the other antennae, which are predominantly dark brown.

distribution and habitat

The species is distributed in Europe north of the British Isles and southern Scandinavia, east to Siberia and Mongolia. In Central Europe it is more common, especially in the montane altitude range. In the Alps it rises to over 2000 meters above sea level, in the lowlands it is not so common and only occurs locally.

Way of life

The animals live on conifers and are said to be found on spruce ( Picea ), fir ( Abies ) and pine ( Pinus ), but in Germany they are only found on European larch ( Larix decidua ). They predatorily feed on aphids of the genera Cinara and Lachnus, as well as fringed winged birds and small caterpillars. The wintering takes place as an imago under bark scales. The females lay their eggs from May to June. The nymphs can be found from June to August, from August you can meet the adults of the new generation. One generation is trained every year.
