The butterfly has a wingspan of 50 to 55 mm. The base-colour of the wings is a rusty red, and at each wingtip it bears a distinctive, black, blue and yellow eyespot. The underside is a cryptically coloured dark-brown or black. There are two subspecies, I. io caucasica (Jachontov, 1912) found in Azerbaijan and I. io geisha (Stichel, 1908) found in Japan and the Russian Far East.
