Acalypta parvula is a bug from the family of net bugs (Tingidae).
features
The bugs become 1.6 to 2.5 millimeters long. The very small bugs of the genus Acalypta usually have shortened (brachyptere) wings and a rather oval body shape. The fourth segment of the antennae is wider than the third and the head has two appendages in front which arise between the antennae. Acalypta parvula has three keels on the pronotum and its third antennae is thickened at the base. Fully winged (macroptere) animals often appear with her. These are mostly females.
distribution and habitat
The kind is found in North Africa and Europe, over the western Mediterranean area to the south of Scandinavia and in the east to the north of Russia. It is also common in North America. In Germany it is widespread and mostly common, only in the low mountain ranges it is rarer and partly absent in the Alpine region. It is rarer in Austria, but rises in the Alps to around 2000 meters above sea level. It is the most common species of its genus and widespread in the UK. Dry, warm and open habitats are settled, and occasionally more humid places. They are found mainly on sandy soils, less often on stony or loamy soil.
Way of life
The animals live mainly in the litter , but like Acalypta gracilis they occur in mosses, but can also be detected far away from them. You probably live in Thymianen ( Thymus ), sedum ( Sedum ), heather ( Calluna ), broom ( Genista ) and other higher growing plants. The species is often found near ant nests, to which, however, they have no relation. This closeness is due to the habitation of the litter. Macroptere animals can fly well and colonize new habitats, which is why they are often found in large numbers in such new locations. The adults hibernate. The nymphs appear from late April to early August. The adult animals of the new generation are sexually mature in autumn, mating takes place in September and October before hibernation. It is not known whether eggs are laid before that. Mating can be observed again in May of next year. One generation is trained every year, but at least in temperature-favored, dry habitats in southern Germany, two generations should develop per year.
