The cow-wheat - Pug occurs in almost all of Europe. The eastern spread even as far as Siberia to the Urals, Central Asia and the Altai Sayan Mountains and the Amur region and in. In the Alps, it is still found in 2000 meters, in the Pyrenees in 2400 meters above mean sea level. In Ukraine, in Asia Minor, the Caucasus and Georgia is the ssp. E. lutosaria home.
