The Caterpillars are attended always by the small black ants :

Anonychomyrma itinerans, or

Anonychomyrma gilberti ( DOLICHODERINAE ),

which typically nest on the same tree that the Caterpillars are on.

The Caterpillars have been found feeding on the foliage of a variety of plants, including :

Terminalia subacroptera ( COMBRETACEAE ),

Box Mistletoe ( Amyema miquelii, LORANTHACEAE ),

Acacia humifusa ( MIMOSACEAE ),

Sydney Red Gum ( Angophora costata, MYRTACEAE ),

Grey Box ( Eucalyptus moluccana, MYRTACEAE ),

Jinggul ( Lophostemon grandiflorus, MYRTACEAE ),

Weeping Paperbark ( Melaleuca leucadendra, MYRTACEAE ), and

Alphitonia obtusifolia ( RHAMNACEAE ),

initially feeding communally and sketetonising the leaves. Later the Caterpillars separate and feed on the leaves nocturnally. By day they hide in crevices on the tree.

They pupate in a nest of their attendant ants. The pupa is mottled brown, and has a length of about 1.3 cms.

Underneath, both sexes are pale brown with arcs of orange dashes outlined in metallic green. The undersides of the forewings also each have two or three black spots. The butterflies have a wingspan of about 3 cms.

The Caterpillars hatch from small clusters of white spherical minutely spined eggs, laid on leaves, stalks, or bark of a foodplant.

This species is found from Cooktown to Sydney in Australia.
