Macrodema microptera is a bug fromthe Rhyparochromidae family .
features
The bugs are 3.1 to 3.9 millimeters long. The shiny dark colored bugs are hairless. The sides of the pronotum are closely keeled. The wings and the back of the pronotum are brown and have dark dots. The thighs ( femora ) of the front legs do not have thorns. The species is usually micropter, i.e. has receded wings, but macroptere (fully winged) individuals also occur.
distribution and habitat
The species is distributed from the Atlantic influenced part of Europe over the south of Scandinavia to the north of the Iberian Peninsula. It becomes rarer in the east, where the distribution area extends through central and northern Europe to Russia. The species is widespread in Germany, but is significantly more common in the north than in the south. Only in the north-west German lowlands is it very common in places. In Austria the occurrence is mainly limited to the Alps. The species is otherwise only locally and rarely distributed here. It is characteristic inhabitants of heather -Heiden and others of ericaceous (Ericaceae) dominated habitats, both marsh, dry sand and limestone soils. They can also be found in partially shaded places such as sparse pine forests with undergrowth with heather plants. The species prefers dry, temperature-favored and sunny habitats with sandy soils.
Way of life
The animals mainly live on the ground, where they suckle on seeds. Rarely climbing imagines to suck on the plant. Occasionally, predatory diets can also be observed. The species often co-occurs with ants, although apparently there is no relationship to one another. The adults overwinter among the food plants and mate in April and May. From May to July, the eggs are laid in the litter or in woody stalks of the common heather. The adults soon die afterwards. The nymphs of the new generation can be observed from June to August, and the first adults appear from the second half of July. The males are able to reproduce as early as November, the females only form mature eggs through artificial warming before overwintering.
