The Caterpillars are initially orange with black hairs. Later they become black, and later still mottled grey and green and brown. They are well camouflaged, and look like the flowers and developing fruit on which they feed. They are gregarious and inclined to stay in clusters.

They feed on various stinging trees ( URTICACEAE ) including :

Gympie Bush ( Dendrocnide moroides ),

Shiny Stinging Tree ( Dendrocnide photinophylla ), and

Australian Mulberry ( Pipturus argenteus ).

The pupa is dark brown and spiky, with darker tips to the spikes, and a white spot under each side of the thorax. The pupa hangs from a leaf or twig, often several hanging together from the same support.

The wings of the male and female adult butterflies are different.
