General color, like most species of this genus, dark brown on the front wings and light gray on the back.On the front wings extends across the middle and a few random uneven almost white sash; closer to the outer edge of the same color goes wavy line; between the latter and sling a little closer to the front edge, there are black staining on the hind wings stand out over a light background two dark lateral stripes and the midpoint. [131].
Imago lifespan
- Butterflies appear in the middle of August and fly until the second decade of September in the mountainous spruce-fir taiga; They rarely occur in pine-fir plantations, occupying the lower slopes of the mountains (400-500 m) above sea level. [131].
