These Caterpillars have a series of black bands running along the back and yellow bands along each side, all broken into rectangles by sets of intersegmental transverse white bands. The head is orange and the thorax yellow. The Caterpillars feed on :

  • Burny Bean ( Mucuna gigantea, FABACEAE ), and
  • Red Jade Vine ( Mucuna novoguineensis, FABACEAE ).

    They grow to a length of about 4 cms. They live in a shelter made by cutting and folding a leaf and joining it by silk. They pupate in the same shelter. The pupa is totally covered in a waxy white powder.

    The adult butterflies are dark brown on top, tending to green at the body. The underside is dark metallic green, with some vague pale green iridescent bands across each forewing, and with a broad pale yellow band across each hindwing. The butterflies have a wingspan of about 4 cms. They rest typically hanging upside-down under a leaf.
