The caterpillars feed on the vines in MENISPERMACEAE such as

  • Long-leaved Milk Vine ( Parapachygone longifolia ), and
  • Common Milk Vine ( Pycnarrhena novoguineensis ).

    The caterpillar pupated in a loose cocoon of torn paper strewn around in the bottom of the cage, up against the vertical wall of the cage.
