Tussock moth caterpillar

Description:

A caterpillar about 25 mm long with four white ill-defined dorsal tussocks on a narrow body covered with soft long pale lime-green setae. the dorsal side of the caerpillar had a narrow band of black and red patternsa and a couple of bright yellow bands near the head. A pair of pencil thin dark forward pointing tufts were seen with hairs of equal length. The rear end had some long grey hairs, again not in a well-defined tuft.
Two red dorsal glads could be seen in the last segments.
The caterpillar looked a little feeble.

Habitat:

Spotted on silver wattle ( Acacia dealbata) in a national park.
