White Lerp Insect - Glycaspis (Glycaspis) fuscovena or G. eucalypti

Family Psyllidae 

This page contains pictures and information about White Lerp Insects that we found in the Brisbane area, Queensland, Australia.
Diameter 3-4mm
The white materials on gum leaves, known as lerps, are the coverings of insect nymphs that live and feed underneath. The insects suck the plant sap and use the excess starch to make those lerps. There are the excess sugar, or the honey dews, that make the ants like to attend for them.

The Lerps Insect adults are winged and look like a very small treehopper. Those White Lerps can easily be found on different species of Gum tree leaves in Brisbane.
Different ant species were found attending the White Lerp insects. They include the Golden-tailed Spiny Ants, Large Purple Meat Ants and Black Tyrant Ants.

Eggs were laid evenly on leaves in batch. The eggs are laid on the surface of the leaves, and the first instars, having emerged and found a suitable site to feed, settles down and begins to construct the lerp. There are five instars each of which adds to the lerp, The last instars moves out from under the lerp before the adult emerges.

Those White Lerp Insects usually feed and hide under white lerp cover. Sometimes we see a nymph freely walk around.
