Its distribution area covers the temperate zone of Northern Hemisphere. In central Europe, it is scattered to rare, mainly in montane valleys. There are historical records from various places in the Czech Republic (e.g., Nádvorník 1947), but recently it has only been found at three localities in the Šumava Mts.
