This is the largest Lerp Insect that we ever found. Lerps insects are closely related with Scale Insects. Like Scale Insects, they are sap suckers and often aggregate in colonies. Lerp-insects appear to take the place of the Aphids on Eucalypt and Acacia.

They insert their stylets, or mouthparts, into the plant and begin feeding and constructing a lerp, the protection cover. Lerps are formed from the sugar and wax excreted by the insects. Those materials harden on contact with air to form the protection. Lerps vary in size with shape of shell and dark brown in colours.
