We found eggs of this species on the trunk of a small Bottlebrush ( Callistemon, MYRTACEAE ). When the Caterpillars hatched, they refused to eat a wide variety of leaves offered. They were reared to adults on wet bark coated with

  • Lichen.

    The caterpillars are grey and black, with orange spots on its sides, and yellow speckles on its back and underside. Also two white lines run along the back. The Caterpillars have long fine hairs which project to the front, to the rear, and sideways. They grew to a length of about 1.5 cms.

    They each formed a pupa inside a net-like cocoon made of silk and larval hairs, attached to the bark.

    The adult male has a pattern of light and dark grey on the forewings. The pattern is very varaiable. Pale specimens have nearly white forewings with a sparse network of dark lines. Dark specimens have nearly black forewings with a few white spots. The hindwings are less variable, and usually orange with a black apical patch, and with a black border that does not extend as far as the tornus. The wingspan of the males is about 1.5 cms.

    The adult female has a length of about 1 cm. She is wingless, and has a brown hairy body with mauve bands. The female stays near her cocoon, and the male copulates with her there. The eggs are laid on the cocoon.
