The red soft bug ( Deraeocoris ruber ) is a bug from the family of soft bugs (Miridae).

features

The animals are 6.6 to 7.7 millimeters long. Their basic color varies from red-orange to almost completely black. As a rule, the cuneus of the hemielytras is more or less strongly colored red. The males are darker in color than the females.

Occurrence and habitat

The species is distributed throughout Europe (with the exception of the far north), North Africa and further east to the Caucasus . She was also abducted to North and South America and performs locally there. In Central Europe it occurs everywhere and is common, but it is much rarer in the north and in the higher elevations of the low mountain ranges. The herb, shrub and tree layers are colonized, although the species is not restricted to any specific plants. However, they are mainly found on the great nettle ( Urtica dioica ), Rubus species, goat clover ( Cytisus ) and thistles . Deciduous trees, including fruit trees, are preferred on woody plants, but the bugs are only rarely found on coniferous trees such as pine ( Pinus ), larch ( Larix ), arborvitae ( Thuja ) and juniper ( Juniperus ), where tree lice (Lachnidae) live. The species also colonizes forests, but occurs mainly on sunny forest edges and open habitats.

Way of life

The species predatory feeds on various small arthropods such as small caterpillars , but especially on aphids . The prey is quickly killed and sucked out by a sting that is also painful for humans. It is therefore considered a beneficial insect in agriculture. The females lay their eggs in August and September. The hibernation takes place as an egg, from which the red-brown nymphs hatch in May, with prickly reinforced abdomen . The adults appear mainly in July and August and become increasingly rare from the end of September. In the Mediterranean region and possibly also in more temperature-favored places further north, two generations arise per year.

Taxonomy

The species was described by Carl von Linné as Cimex ruber in his work Systema naturae . Today it is placed in the genus Deraeocoris within the soft bug subfamily Deraeocorinae .
