These Caterpillars are initially green, with a dark brown head. Later instars become brown with a green, brown, or pink head, and have dark dorsal and lateral lines. Both head and tail each have a pair of horns.
The caterpillars feed on the leaves of various Grasses ( POACEAE) including :
The caterpillars hide in the base of the tussock leaves during daylight, feeding nocturnally on the tips of the leaves. They grow to a length of about 3 centimetres.
The pupa is brown with dark markings, suspended from a cremaster, usually on a leaf or stem of the foodplant.
The adult butterflies have a wing span of about 4 cms. The upper surfaces of the wings are orange with dark brown markings, and an eyespot on each wing. The males have a grey-brown band across each forewing. The wingspan is about 4 cms.
The undersides are yellow with brown markings, and one eyespot on each forewing, and two on each hindwing. The butterflies normally rest with wings closed. The butterflies fly close to the ground and settle frequently, so using their camouflaged underside to avoid detection.
The eggs of this species are cream and spherical, with a diameter of about 0.8 mm. They are laid in groups of 1,2, or 3 on a foodplant leaf.
Two sub-species have been recognised :
