The caterpillars pupate within the emptied seed case, attaching it to the tree so that it does not fall to the ground. The pupa is smooth and pinkish-brown with dark markings.

The eggs are white, round and flattened, with a diameter of about 1 mm. They are laid singly on fruits of the foodplant.

This species is found in

northern Queensland,

and occurs widely throughout the Cape York Peninsula south to Undara Crater.

The riparian thickets along the lagoon and stream edges include dense stands of Strychnos lucida. The fruits on these trees support a large population of the butterfly.
