Sphragisticus nebulosus is a bug fromthe Rhyparochromidae family .
features
The bugs are 4.2 to 5.5 millimeters long. They are similar to species of the genus Peritrechus , but they can be distinguished by the edge of their pronotum . He is pale, keeled and has five to seven hairs that arise from dark spots.
distribution and habitat
The species is distributed holarctic . It occurs in northern and central Europe and is absent in western and southern Europe. In the east, the distribution extends to Central Asia and Siberia. It is also common in North America. It is widespread in Germany, common in the north and east and increasingly rare in the south-west. Occasionally the animals appear en masse. It is rare in Austria and occurs mainly in the east. In Great Britain it is only known from the Brecklands of East Anglia , where it was first detected in 1997. Mainly open, dry, warm habitats such as dunes, sandy grasslands and sandy cultivated land as well as ruderal areas are settled. They are rarely found on other soils.
Way of life
The animals mainly live on the ground and rarely climb up on the plants. They suck on seeds that have fallen on the ground and are apparently not picky about their food plants. They can be found in the ground litter, for example, under the foxtail family (Chenopodiaceae), cruciferous family (Brassicaceae) and predatory leaf family (Boraginaceae). Two generations are likely to be trained per year, but they overlap, so that no reliable delimitation can be made. The adults hibernate and mate in April. The females lay their eggs in the litter. From May you can find the nymphs , which molt into adults by mid-June. This new generation lays their eggs in July and August and most of the nymphs can be found again in September. The adult animals of the next generation appear until the end of October and can be active until November.
