Nysius thymi is a bug from the family of ground bugs (Lygaeidae).
features
The bugs become 3.5 to 4.5 millimeters long. The species is difficult to distinguish from the other species in the genus Nysius . Nysius ericae in particular is very similar. Both species lack the easily recognizable dark ring at the base of the second antennae and both have dark spots on the wing membrane. The safest way to determine this in males is through a genital examination. The females can be distinguished by the hairs on the veins of the wings, which are shorter than those of the similar species.
distribution and habitat
The species is distributed Holarctic and occurs all over Europe, east to Siberia, Central Asia and China. In North America, they are found in the United States, including Alaska and Canada. In Central Europe it is widespread and rises in the Alps to around 2000 meters above sea level. The species can be found in large numbers in favorable locations. It prefers open, sunny sand and limestone locations with low, gaps in vegetation.
Way of life
The animals live on a large number of different daisy family (Asteraceae), but also on mint family (Lamiaceae) such as z. B. thyme ( Thymus ), cruciferous (Brassicaceae) such as cress ( Lepidium ) and other plant families. The young nymphs suck seeds on the ground, imagines suck frequently at immature seeds of the plants. Wintering is usually done as an egg. However, depending on the temperature, it is possible that nymphs can be observed even in winter. In addition, individual adults of the old generation can be found well into winter. The bugs occur in Central Europe in two generations per year, with the nymphs mainly to be found in May and June, as well as in September. Mating mostly takes place in June and July and September and October. The females lay their eggs in small groups on the food plants.
