Thanks Martin. There were actually a couple of D immaculata adults on other plants in the area.

Mark, I have pondered your beetle larva and decided I was wrong to call it calomela. Dicranosterna immaculata is also a bipinnate acacia feeder. It has spotted globular larvae which I have seen several times. http://www.projectnoah.org/spottings/427...

This larva would have been a bit larger than any Calomela.

The globular larvae are calomela and my images might be differen species or early instars.

And the Peltoschema larvae are larviform.
