Male: Upperside brown, both fore and hind wing with terminal margins much darker, and generally with more or less distinct subbasal and discal dark bands. Fore wing with a large, slightly oblique, oval, bi-pupilled, yellow-ringed black, pre-apical ocellus. Hind wing with two postdiscal, round, uni-pupilled, similar but smaller ocelli, and very often one or two minute tornal ocelli also. Underside similar to the underside in Y. philomela but the ochraceous-white ground-colour paler, tin-transverse brown strice coarser, the ocelli on the hind wing more distinctly in echelon, two tornal, two median, and two pre-apical, and on both fore and hind wing more or less distinctly defined, subbasal, discal and subterminal brown transverse bands. Female: Differs on the upperside in having the area surrounding or bordering the ocelli on both fore and hind wing paler, closely irrorated with brown striae, the discal transverse band generally clearly defined, and very often both the tornal, and at least one of the apical, ocelli distinct. On the underside it is paler than the male, and has the subbasal, discal and subterminal transverse dark bands more clearly defined.[1]
