The Caterpillars of this species have been found boring into saplings of plants from a number of families, including

  • Snow Daisy-bush ( Olearia lirata, ASTERACEAE ),
  • Silver Wattle ( Acacia dealbata, FABACEAE ),.
  • Mountain Ash ( Eucalyptus regnans, MYRTACEAE ),.
  • Dogwood ( Pomaderris apetala, RHAMNACEAE ), and
  • Satinwood ( Nematolepis squamea, RUTACEAE ).

    The caterpillars appear to feed for 2 to 3 years, boring downwards less than a metre above ground level, to create a borehole with a depth of about 60 cms. The caterpillars pupate in their borehole.
