These grubs are not true Caterpillars, but are the larvae various types of beetles ( COLEOPTERA ) in the genus Paropsis in the family CHRYSOMELIDAE. 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. 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 2 cms.

    The adult beetles are typically brown, and also often feed on the foliage of the same tree as the larvae.
