Megalonotus sabulicola is a bug fromthe Rhyparochromidae family .
features
The bugs are 4.0 to 5.0 millimeters long, making them the smallest representatives of their genus in Central Europe. Like all representatives of the genus, they have a darkly colored pronotum, especially roughly dotted at the back . The thighs ( femora ) of the front legs have a long tooth and several small teeth. Megalonotus sabulicola can be identified by the fact that its pronotum has long, upright hairs and the rear edge of the pronotum is evenly curved. In the similar species Megalonotus emarginatus , the corners protrude at the rear edge of the pronotum and are angled backwards at an acute angle. The splints ( tibia ) of the middle and rear legs are pale in color, in Megalonotus chiragra they are dark. The second and parts of the third antenna segment are also pale. Unlike Megalonotus chiragra , most animals are fully winged (macropter).
distribution and habitat
The species is distributed from the north of the Mediterranean to the extreme south of Scandinavia and the British Isles. In the east the distribution area extends to Siberia and Central Asia. The species is also found in Japan and was introduced to the northwest of North America. It is presumably widespread in Germany, but has only been found sporadically in the northern German lowlands and is not common. It is widespread and common in Austria. It is rare in the UK and only occurs in the south of England. Mainly dry, warm and open habitats with sandy and chalky soils are settled. The species requires more warmth than Megalonotus chiragra , from which it was previously indistinguishable.
Way of life
The animals are polyphagous and not bound to any particular food plants. They suck on the seeds of the plants. In North America, two generations are trained each year.
