Habitat:
Stenobothrus eurasius inhabits steppe-like dry grasslands which are usually interspersed with rocks. In the Northwest (e.g. East Austria) very steep and dry, rocky slopes are the core habitats. In other regions also more plain but always gappy vegetated steppe grasslands may be settled.
Life cycle:
The adults appear quite early with peak between mid-June and late July. But also later (e.g. mid-September 2017, E-Austria) some individuals may be found, especially females. In hot conditions the animals sometimes rest in somewhat denser grassy vegetation directly next to their essential rocky and gappy nutrient-poor habitats.
Endangerment factors:
Stenobothrus eurasius is heavily endangered in Europe due to habitat loss (eutrophication, bush encroachment and densening of vegetation after abandonment, locally also overbuilding and tourism).
Remarks:
Stenobothrus eurasius occurs in several subspecies from E-Austria to Mongolia. In Europe the populations are usually small and strongly isolated (from E-Austria, Slovakia and Czech Republic to mainland Greece, Romania, Ukraine and S-Russia).
