These Caterpillars are green, segmented, and hairy. They feed on the flowers of such plants as :

  • Gray Nicker ( Caesalpina bonduc, CAESALPINIACEAE ),
  • Cheese Tree ( Glochidion ferdinandi , PHYLLANTHACEAE ),
  • Poison Peach ( Trema tomentosa, ULMACEAE ), and
  • Australian Mulberry ( Pipturus argenteus, URTICACEAE ).

    The male adult butterflies of this species are lilac on top, whereas the females are brown. Both have a little tail at the tornus of each hind wing. The males have one or two black spots beside each tail. The females have a whole arc of black spots along the margin of each hind wing.
