Adults have rounded wings; the upper side of the wings, both front and rear, is dark brown almost black, the lower one is brown / orange, with black ocelli surrounded by a yellowish border and a dot of the same color in the center of the ocello, 3 ocelli on the front wing and 4 or 5 on the rear wing.
The females are larger than the males, with more developed ocelli and often visible also on the upper side of the hind wings.
