Oeneis magna Graeser, 1888
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.
This species in the Altai Mts. inhabits open coniferous forests of a subalpine belt, close to the tree line. Males usually perch on tree trunks and dry branches. They may fly far away when chasing intruders but as a rule return. They usualy have several closely situated perches and rest on either of them.
