These Caterpillars are green or brown, with orange ends. The front end has black spots, and the head is brown. It feeds inside the large seeds in fruit on various trees, for example :

  • Blue Quandong ( Elaeocarpus angustifolius, ELAEOCARPACEAE ),
  • Mock Orange ( Pittosporum undulatum, PITTOSPORACEAE ),
  • Queensland Nut ( Macadamia tetraphylla, PROTEACEAE ),
  • Shell Vine ( Connarus conchocarpus, CONNARACEAE ),
  • Tulipwood ( Harpullia pendula, SAPINDACEAE ).

    The Caterpillar is often attended by ants, including those from the species :

  • Hagiomyrma lydiae ( MYRMICINAE,
  • Cyrtomyrma australis ( MYRMICINAE,
  • Phaeidole megacephala ( MYRMICINAE ), and
  • Technomyrmex albipes ( DOLICHODERINAE ).

    The pupa is dark brown, and formed within the hollowed-out seed.

    The adults are dimorphic: the males and females being different. The tops of the wings of the males are black, with a large bright orange patch on each wing. The females are grey with a dark leading edge to each forewing.

    Underneath, both sexes are fawn with white wiggly lines. They both have two tails on each hind wing: a thick one and a thin one. The thick one has a black eye-spot on it ringed with orange, and there is another just beside each thin tail. Presumably, the thick tail looks like a fake head, and the thin one looks like an antenna, and with the eye-spots these are useful for confusing predators about which end of the animal is which.

    The butterflies have a wingspan of about 3 cms.

    The eggs are green, rough, round, and flattened, with a diameter of about 0.8 mm. They are laid singly on fruit of a foodplant.
