Raglius alboacuminatus is a bug fromthe Rhyparochromidae family .
features
The bugs are 5.4 to 6.3 millimeters long. They have a conspicuous red-brown and white pattern on the hemielytres and the posterior third of the pronotum . There is a large white spot on the hemielytric cuneus. Both individuals with shortened (brachypter) and fully developed (macropter) wings occur.
distribution and habitat
The species is distributed from North Africa across Europe, with the exception of the north and east to western Siberia and across Asia Minor to the Caspian region. It was introduced into North America by humans. It is widespread in Germany, but is absent almost everywhere in the northwest. It is not uncommon in the south and can be common in places. In Austria it is also widespread and not uncommon. In the Alps, however, they can only be found in the valleys. It is rare in Great Britain and is particularly common in the south, especially the south-east. Various warm and dry, moderately moist habitats are settled, preferably with calcareous soils and with vegetation of deciduous and coniferous trees, such as forest edges, clearings, hedge borders, bushy grasslands or fallow land.
Way of life
The animals often live among the mint family (Lamiaceae), such as black nettles ( Ballota ), horehound ( Marrubium ) and ziesten ( Stachys ), but they are apparently not bound to certain food plants. Both the nymphs and the adults stay almost exclusively on the ground and rarely climb on the plants to suckle on the ripening seeds. The adults overwinter under loose bark or dead wood. Often the animals gather to form large aggregations. These can also be found in summer, however, together with the nymphs. They are not completely inactive during the winter and can also be active in January and February at higher temperatures. The mating mainly takes place in May. The females lay their eggs one by one in the litter . The nymphs can mainly be seen in June and July, the new generation of adults from July. In the south of Germany, in favorable years, a second generation can also appear with adult animals from September.
