features
The white-point ground bug has a black head, a black scutellum , black antennae and black legs. There are two hook-shaped black spots on the red pronotum. The corium of the hemielytres (the partially hardened fore wings) is red with a black round spot in the middle, while the membrane (the transparent part of the fore wings) is black with a white round spot in the middle. The connexive (part of the abdomen visible on the side) is red with black spots. The bug reaches a body size of 6.9–7.3 mm.
distribution and habitat
The warmth-loving type of bug is very common in the Mediterranean region. Their distribution area extends in the east over Asia Minor to the Caspian Sea . In Central Europe, the white-point ground bug occurs only sporadically and is mostly limited to so-called "heat islands". In Germany these are in the Upper Rhine Plain and on the Middle Rhine . The bug species is also found on the northern French Channel coast, in the Netherlands and in Austria.
Way of life
The bug species prefers hot, dry, rocky habitats - rarely areas with sandy soils. She is a so-called seed sucker. The main food plant of the white-point ground bug is swallowwort ( Vincetoxicum hirundinaria ). Further forage plants are the red foxglove ( Digitalis purpurea ) and plants from the genus of the ragwort ( Senecio ). The adult bugs of the species overwinter.
