There is marked sexual dimorphism in this species. The upperside of the male is uniformly light brown with a black ocellus centered white at the apex of the forewing, while the female has a tawny patch more or less extended around this ocella. The underside forewing is ochre-colored bordered with dark beige with the same ocelli at the apex in the male, while the hindwing is greyish to brown with a more or less orange band in the female. Above dark brown: the apical ocellus minutely centred with white, being in the male bordered with dull dark yellow, and standing in the female in an ochre-yellow half band, which becomes narrower behind and does not reach the hindmargin. The upperside of the live male has often a splendid metallic gloss and bears a broad scent-patch below the cell. Underside of hindwing in the male dark brown, with a hardly perceptible middle band, in the female grey-brown, with a broad, pale, proximallv golden-brown-bordered curved band. In several forms throughout Europe Apart from the forms characterized by the disappearance of ocelli or the appearance of accessory there are firstly the albinos which have received in which the blackish ground-colour is replaced by dirty white, while the reddish yellow halfband has remained as such. In others the reddish yellow halfband on the forewing of the female is pale to ivory-white. Specimens have been described in which the band of the male is very prominent on a silky dust-grey upperside. Aberration cinerea has a bluish gloss on the dark upperside; the hindwing is strongly dentate, tinged with pink on the underside, and bears two eye-dots In hot summers one not seldom meets with specimens in which the reddish yellow colour has increased, this colour being represented by a yellowish red dusting on the apical area in the male and in the female by a yellowish red area in the disc of the hindwing. The live male has in its apical area a magnificent golden gloss on a deep black ground, in the female the ground-colour above is reduced by the extension of the reddish yellow. Moreover, the form is much larger and the basal area of the hindwing is so darkened below that the light discal band contrasts vividly. A variable number of smaller eyespots are usually found on the hindwing undersides. These may number up to twelve per butterfly, with up to six on each wing, but sometimes none. The egg is upright and ribbed; the top is flattened, with an impressed ring thereon. Color, whitish green inclining to brownish yellow as it matures, and marked with purplish brown. The caterpillar is bright green, clothed with short whitish hairs; there is a darker line down the back, and a diffused white stripe on each side above the reddish spiracles; the anal points are white. Head rather darker green, hairy. The chrysalis is pale green, marked with brownish on the wing covers, the thorax is spotted with blackish, and the points on the body are brownish. Suspended, and with the old skin attached.
