The caterpillars live in leafy shelters by day. Initially these are constructed from a cut piece of leaf folded over to make a triangular pocket. Later instars join two leaves together with silk. The caterpillars feed nocturnally on various trees, including :

  • Custard Apple ( Annona reticulata, ANNONACEAE ),
  • Queensland Cascarilla ( Croton insularis, EUPHORBIACEAE ),
  • Bolwarra ( Eupomatia laurina, EUPOMATIACEAE ),
  • Camphor Laurel ( Cinnamomum camphora, LAURACEAE ),
  • Hibiscus ( Hibiscus rosa-sinensis, MALVACEAE ), and
  • Brush Box ( Lophostemon confertus, MYRTACEAE ).
