The eggs of this species are round, white and flattened, with a diameter of about 0.8 mm. They are laid in spring in groups at the base of the foodplant, typically by the nest of the small black ants :

  • Coconut Ant ( Papyrius nitidus, DOLICHODERINAE ).

    If there is no ant nest already at the base of the plant where the eggs are laid, the ants actually come and build one.

    The Caterpillars are fawn and velvety, with a broad dark dorsal band, and zig-zag black and yellow lines. By day the Caterpillars shelter in the ant nest, and are shepherded by the ants to the new shoots in the evening, and back to the nest at dawn. The Caterpillars feed on a wide variety of plants, including:

  • Daphne Heath ( Brachyloma daphnoides, EPACRIDACEAE ),
  • Dogwood ( Jacksonia scoparia, FABACEAE ),
  • Wattles ( Acacia, MIMOSACEAE ),
  • Gum Trees ( Eucalyptus species, MYRTACEAE ),
  • Red Ash ( Alphitonia excelsa, RHAMNACEAE ),
  • Blackberry ( Rubus fruticosus, ROSACEAE ),
  • Native Cherry ( Exocarpus cupressiformis, SANTALACEAE ),
  • Carrotwood ( Cupaniopsis anacardioides, SAPINDACEAE ), and
  • Camellia ( Camellia japonica, THEACEAE ).

    The pupa is a mottled brown, and normally occurs inside the nest of the host ants. It has a length of about 1.3 cms.

    The adult male and female butterflies look very similar. On top, they are basically dark brown, with a blue iridescent sheen.

    Underneath: they have patterns like flames: yellow with scarlet bands outlined in black, white, and iridescent green. This is presumably the origin of their scientific name, derived from 'ignis', the Latin word for 'fire'. There are also three or four black spots under each forewing.

    The butterflies have a wing span of about 3 cms.

    The species occurs as a number of races in

  • New Guinea,

    and around much of the coast of Australia, including

  • Western Australia,
  • Northern Territory,
  • Queensland,
  • New South Wales,
  • Victoria, and
  • South Australia,

    as the subspecies

  • olliffi Miskin, 1889, in the south of Western Australia,
  • erythrina Waterhouse & Lyell, 1909, in the north of Western Australia and the Northern Territory,
  • chrysonotus Grose-Smith, 1899, in northern Queensland, and
  • ignita in southern Queensland, New South Wales, Victoria, and South Australia.
