This Caterpillar is smooth and yellow, with various black markings, including a dorsal line, and a transverse band between each pair of segments. The head is yellow with two transverse black stripes. It lives on its food plant in a shelter made from a leaf, folded over and held with silk. It feeds on:

  • False Almond ( Terminalia catappa, COMBRETACEAE ),
  • Yellow Wood ( Terminalia oblongata, COMBRETACEAE ),
  • Australian Damson ( Terminalia seriocarpa, COMBRETACEAE ), as well as
  • Pongam ( Pongamia pinnata, FABACEAE ) and
  • Timor Liana ( Rhyssopterys timorensis, MALPIGHIACEAE ),

    living in a partly folded leaf, open ended like a cup. The Caterpillar grows to a length of about 5 cms.

    It pupates in a partly folded leaf, often away from the food plant.

    The undersides are similar to the upper surfaces. The hindwings of both sexes are unusual, in having a recurve along the margin near the tornus. The wing span is about 5 cms.

    The eggs are cream coloured and hemispherical. They are laid singly on young shoots of a food plant.
