This caterpillar is green with several black-edged white stripes along the back and sides. The head is either green or brown, with black spots. The caterpillar has a reduced number of prolegs, and so moves in a looper fashion. When disturbed: it thrashes its head and tail from side to side. It has been reported feeding on:

  • Amaranth ( Amaranthus, AMARANTHACEAE ),
  • Croton ( EUPHORBIACEAE ),
  • Sida ( MALVACEAE ), and
  • Heartseed ( Cardiospermum, SAPINDACEAE ).

    The adult moth has rusty brown wings, with a number of thin sinuous pale lines across, and a variable white mark near the middle, of each forewing. The hindwings are plain brown. The moth has a wing span of about 2 cms.

    There is a lot of confusion about whether this is the same as Amyna octo, and the names are just synonyms.

    The species is found around tropics, including

  • Cook Islands,
  • Japan, and
  • U.S.A.,

    and also in Australia in

  • Queensland.
