The Asopinae are a subfamily of the stink bugs (Pentatomidae) from the suborder Pentatomomorpha . In English, the bugs are called Predatory Stink Bugs (" Predatory Stink Bugs ") or as Soldier Bugs (" Soldier Bugs ").

features

The bugs reach sizes between 7 and 25 mm. The representatives of the Asopinae are distinguished by their proboscis (rostrum) within the stink bug family. Its basal segment is short, thick and freely movable. Only the base is located between the buccules (the cheek plates laterally delimiting the beak groove), which unite below the trunk. The proboscis are at least twice as thick as the antennae. Other representatives of the stink bug have a slender base of the first trunk segment, which is embedded between the buccules. The buccules in these have a greater distance and run parallel.

Way of life

The representatives of the Asopinae predatory feed on arthropods . They usually have a wide range of prey, which mainly includes slow-moving insects with soft bodies. These include beetle larvae, butterfly caterpillars, but also phytophagous stink bugs of the subfamily Pentatominae . The prey animals are drilled with the proboscis and sucked out. The nymphs in the first stage still feed on vegetal food, while the second to fifth nymph stages have a predatory diet. Since many prey animals are considered to be agricultural pests , the Asopinae bugs are considered beneficial insects and are sometimes used in the context of integrated pest management.

Taxonomy and systematics

There is no generally accepted division of the subfamily into tribe . 69 genera are known. There are around 300 species worldwide. In Europe the subfamily is represented with 13 species from 10 genera. There are 35 species in 16 genera in the United States .

The Asopinae include the following genera:
