Habitat:
Yersinella beybienkoi inhabits vertically structured areas such as dwarf-shrub-rich grasslands, forbs, scrub and similar places between app. 700 and more than 1600m.

Life cycle:
The adults occur between July and October. They are often very inconspicuous.

Remarks:
Yersinella beybienkoi occurs locally in the SW-Alps of France and Italy and a bit more numerous in the Apennines (e.g. Abruzzes).

Hints on determination:
The male cerci show a straighter innerline (dorsal view) than in raymondi. The subgenital plate of the females show a larger and more regular semicircular incision.
