Life Cycle:

The eggs are laid in clusters on the leaves and caterpillars are usually observed between September and January. They pupate in litter at the base of the tree or under loose bark.


Origin and History:



Hairs on caterpillar cause skin rashes.

They attack many species of eucalypts with a preference for Jarrah, Wandoo and River Red Gum. Heavy infestations may completely defoliate trees but rarely kill them. Young caterpillars feed in groups, initially on the lower leaves, and reduce the leave to a skeleton of veins. Larger caterpillars feed individually and consume the whole leaf or leave only the midrib.

Management and Control:

Control is only required in very heavy infestations.
