These caterpillars initially are orange with a black head. Later instars become pink with a green thorax and anal plate. They have a dark green line down the back. The live in a shelter made by cutting a piece of leaf and folding it over and joining it with silk. They cling to the roof of their shelter upside-down by day, coming out to feed in the evening. They have been found feeding on the foliage of various trees, including:

  • Billy Goat Plum ( Planchonia careya, LECYTHIDACEAE ),
  • various species of Gum Trees ( Eucalyptus species, MYRTACEAE ),
  • Brush Box ( Lophostemon confertus, MYRTACEAE ),
  • Swamp Mahogany ( Lophostemon suaveolens, MYRTACEAE ), and
  • Jinggul ( Lophostemon grandiflorus, MYRTACEAE ).
