Pergagrapta bella

Description:

I saw this once about 30 months ago and still have no ID. It's back. Still have the little yellow backpack, black ocelli, slightly clubbed short antennae. This time I noticed a bulbous abdomen too. Overall about 22mm long. Found exploring and hovering around fresh eucalyptus leaves seemingly hunting for something but continually resting for short periods on many vacant leaves.

Habitat:

On Eucalyptus microcarpa In an outer urban back yard.
