The first instar Caterpillars of this species are initially green, with a yellow head, a yellow spots on the side of each segment, and a straight dark tail spike.

Later instars are basically black or dark brown, including the head, with a yellow line each side from the head to the first eyespot, and another from the last eyespot to the tail-spike and down the claspers. The eyespots are yellow, with a brown blotch in the lower half, and a straight upper edge. The eyespots on the first abdominal segment contain pale dots. The tail spike is long and black, with a reddish base and a white tip.

In Australia, the caterpillars have been found feeding only on

  • Grass Potato, ( Curculigo ensifolia, IRIDACEAE ).

    The caterpillars can be found by seeking the results of their characteristic feeding beviour. Early instars eat a hole in the middle of a foodplant leaf. Later instars eat a leaf-blade from the tip, leaving it cut squarely across.

    The caterpillars grow to a length of about 8 cms. Pupation occurs in a loose cocoon amongst the leaf litter. The pupa is brown with a dark spot on the side of each segment, and a broken dark line along the back and the underside. The pupa has a length of up to 4 cms.

    The adult moths have brown forewings with a central pale stripe from base to wingtip. The hindwings are red with dark brown outer margins, and pale brown hind margins. The wingspan is about 6 cms.

    The eggs are pale green, and ovoid with a length of nearly 2 mms. The eggs are laid singly on the upper surface of a foodplant leaf.

    The species is found across south-east Asia and the south-west Pacific, including :

  • Borneo,
  • Hawaii,
  • India,
  • New Caledonia,
  • Papua,

    and in Australia in

  • Northern Territory, and
  • Queensland.
