but in Australia, they feed on various species from the family SALICACEAE, namely the Australian native :
and the introduced ornamentals :
The pupa hangs obliquely from a cremaster. It is green with shiny brown projections, and has a length of about 2 cms.
The adult butterflies on top are orange, with black scalloped subterminal lines, and a number of black spots of various sizes. Underneath they are similar but paler, and have a large black spot under the tornus of each forewing. They have a wingspan of about 5 cms.

This species is found as a number of races from Africa to south-east Asia, including :
as well as in Australia in
It has been suggested that the patterns on the wings of this species have evolved to mimic those of the poisonous species in the butterfly genera Taenaris and Hyantis.
