Distribution and biological peculiarities in Armenia: The species is distributed from Spain through Central and South-eastern Europe, Asia Minor, Southern Kazakhstan, and Southern Siberia to Ussuri region of Russi, Korea, and Japan. Armenia is inhabited by nominate subspecies, which occupies deciduous forests in Norhtern and Southern parts of th country except of Southern slope of Meghri Mountain Ridge and residual forest patches of Central Armenia, thus occurring in elevation range from 1000 to about 2200 m above sea level. Number of host plants have been recorded for the species, such as grasses Arrhenatherum elatius, Achnatherum, Molinia coerulea, Calamagrostis, Avena, Bromus, Dactylis, Poa, Festuca, Carex. Such wide specialization of the specie should suggest wider distribution, however it appears that some other factors such as shade in the forest play the role. The species gives one generation per annum, having butterflies on wing from early July till late August.
Population dynamics: In some parts of its range the species considerably rare, while in the others it is slightly uncommon within typical habitat.Population dynamics shows stability during 2003-2013 (p>0.05). The fact that the species is nt occupying degraded forests, makes it one of possible indicators of the forest ecosystems, which could by possible to use in sustainable forestry management.
Conservation measures: The species is not included in the Global and National Red lists, but is assessed for European Red List as a Least Concern. also is not included in CITES and Bern conventions. Preliminary evaluation of its conservation status for Armenia suggests it as a Least Concern. At current the distribution range of the species is covered by some protected areas and Emerald Sites, however the larger part lays within the forestry enterprises and requires careful management of those.
