Wingspan: 2.5-3.5 cm. Adult males and females are similar, with subtle colouration differences on the uppersides of both sets of wings. Males are chocolate-brown except for an orange-brown ‘tail’, females are more reddish or orange-brown except for brown on the wing margins and the area near the tail. Undersides of wings of both sexes are brown with a thin, jagged white line, bordered with black, running across both sets of wings on the inside edge. The hindwing has a small “tail” with a few black dots and bluish and orange scales. Males have larger eyes than females, which may assist in detecting mates. Larvae are green or yellowish-olive with red, green, yellow, or white markings and lighter raised chevrons that somewhat resemble “scutes” (bony protrusions or scales), that run down the dorsal area. Larvae emit a sugary solution through a “honey gland” (dorsal nectary organ). Ants feed on the solution and protect the caterpillar from predators.Hibernating pupae are dark brown.
