These grubs are not true Caterpillars, but are the larvae of the beetle Poneridia semipullata in the family CHRYSOMELIDAE. Initially the larvae are pale yellow with a black head. As they develop, they acquire black warts along the body. Later they become entirely dark grey. They grow to a length of about 1.5 cms. They are often communal, eating in a group the leaves of their food tree. The one illustrated here was feeding on the leaves of:

  • Morton Bay Fig ( Ficus macrophylla, MORACEAE ).

    Other species of beetle larvae in the same family feed on the foliage of other trees.

    The adult beetles are brown with a black mark on the back of the thorax. The adult beetles feed on the foliage of the same trees as the larvae.

    These beetles are found in

  • Western Australia,
  • Northern Territory,
  • Queensland, and
  • New South Wales.
