I don't like to be destructive to any insects I come across but curiosity won this time. I lifted this scale insect to see what was underneath. Not what I expected - a bunch of grubs. I thought there would be a little sap sucking insect! Maybe it has been parasitised?
Ant waits patiently for this armoured bug to excrete some delicious nectar wee. The ant's right antenna is touching the triangular shaped protrusion where the nectar is excreted. Let's call this the tail end. Oxley Creek, QLD.
