Oeneis norna (Thunberg, 1791) - Norse Grayling.

Oeneis is a large genus inhabiting mostly polar and mountain tundras, alpine meadows and screes, forest-tundras, some species inhabit taiga or peat-moss bogs, only few of them penetrate into the steppes. There are an immense number of hardly differing taxa of a problematic rank and range. Some of them seem to be parthenogenetic, that can partly explain ambiquity of species limits in these very cases. The males of Oeneis exhibit the most expressed territorial behaviour among Satyrids and have a very swift and impetous flight. They occupy any noticeable objects disturbing their even habitats.
