Gum Leaf Beetle
(formerly known as Notoclea variolosa)

This grub is not a true Caterpillars, but is the larva of a beetle. The larvae are black and corrugated, with a broad orange dorsal band, and rows of white spots. This one was found on a Gum Tree.
The grubs have the odd habit of elevating their tapered tail in the air, perhaps mimicking the behaviour of Sawfly larvae.
The beetles of the various species in Paropsis are almost hemispherical with a diameter of about 1 cm. These beetles have various coloured patterns according to the species. The larvae of many of the these beetles lift the tail like that illustrated above.
The species Paropsis variolosa is found all over the whole of mainland Australia. Other similar species are found only in Tasmania.
