Description in Seitz

E. cyclopius Ev. (35 c). Upperside grey-brown. The forewing has on both surfaces a subapical, nearly circular, black ocellus with 2 white pupils and ochre-yellow border. The underside of the forewing is somewhat lighter than above and the yellow border of the eye-spot is much wider, the apex of the wing being feebly dusted with bluish grey. The hindwing beneath at the base likewise dusted with bluish grey for a considerable distance; a submarginal band bluish ashy grey, in some places interrupted by the ground-colour. The ocelli of the female are larger and more broadly ringed with yellow than in the male, the apex of the wing being more densely dusted with grey-blue. Antenna ringed black and white, the club russet yellow. — In the Ural, Altai, and Kentei Mts., on the Amur and its tributaries, and on Askold; in May, June and July in damp pine-woods, locally abundant. The largest specimens occur on Askold, having an especially large subapical ocellus.[2]

Adults are on wing from June to July.

The species overwinters in the larval stage.[3]
