Early instars of the Caterpillars of this species are green with a rusty-brown forward-curving tail spike.
The caterpillars feed on the epiparasitic Ant Plants (Mymecodia species, RUBIACEAE), such as
The penultimate instars develop red legs. The final instar is a patchy brown, with pairs of dark triangles along the back.
The caterpillar grows to a length of about 4 cms. The pupa is pale brown, with dark lines where the veins of the wings develop, and a row of dark spots, one on each spiracle, along the sides. The pupa has a length of about 3 cms. It is formed in a silk cocoon in a crevice on the foodplant or its host.

The adult moths of this species have brown forewings, each with one wide and one narrow pale stripe. The hindwings are each dark yellow with a broad brown margin. The wingspan is about 5 cms.
The eggs are pale green and egg-shaped, with a length of about 2 mms. They are laid singly on new growth of a foodplant.
The species occurs in Australia as the subspecies doddi Clark, 1922, which has a convex rather than sinuous submarginal pale arc. The subspecies is found only in
