which are parasitic on
The caterpillars are often attended by various species of ants.
The pupa is mottled brown with a dark line along the back. Its length is about 1.5 cms. It is formed in a crevice often some distance from the foodplant. It is unusual in that it can make clicking noises.
The male and female adults are quite similar, They are both purple on top with broad black wing margins, but the female has a bluer tinge, and more rounded wing-tips.
Underneath, the forewings are dark brown, with white lines emanating from the costa. The hindwings have a complex brown pattern. The butterflies have a wing span of about 4 cms.
Widespread but very local, adults are sighted flying around the tops of eucalypts which support their host. As with all Ogyris, the usual way to obtain adults is to collect larvae and pupae, as the adult butterflies do not feed from flowers, or descend to ground level.
The eggs of this species are dark brown and round, with a diameter just under 1 mm. They are laid in ones or twos on a foodplant.
The species occurs over most of the eastern half of Australia, including
Various races have been proposed :
