The Caterpillars of this species are mottled brown, and live in hollows in the bulbs of various species of Ant Plant :

  • Beccari's Ant Plant ( Myrmecodia beccarii, RUBIACEAE ), and
  • Tuberous Ant Plant ( Myrmecodia tuberosa, RUBIACEAE ),

    which are epiphytes on various coastal trees, particularly:

  • Niaouli Paperbark ( Melaleuca viridifolia, MYRTACEAE ) .

    The caterpillars feed on the interior tissues in the bulb in which it lives, and nocturnally emerges to feed also on the foliage. Its exit hole in its home bulb becomes surround by frass, which is a useful guide to discovering a caterpillar. The same galleries in the plant bulb house a nest of some species of ants, including :

  • the Australian native Golden Ant ( Philidris cordata, DOLICHODERINAE ), and
  • the introduced Tuyaoozuari Ant ( Pheidole megacephala, MYRMICINAE ).

    Only one caterpillar appears to live in any one plant. The ants and the caterpillar seem to ignore each other, the caterpillar apparently feeding on the plant tissues. However, some observers believe that the Caterpillar feeds on the ant larvae, and some believe that the ants farm the Caterpillar.
