Paropsis marmorea is tricky to identify. It is defined by the positioning of the three main blotches on each elytra. These three marks should be compared with the similar Paropsis geographica. To avoid confusing these two beetles, imagine a triangle joining the tree main blotches on each elytra. The line through the top two blotches runs parallel to the suture and the lateral margin of the elytra almost exactly halfway between them.
A large fly with about 30mm wingspan. Solitary and apparently searching for something around the base of a large eucalyptus. A species I haven't seen before. Glenfern valley nature reserve. This one is a male. The females are quite colourful with a lot of yellow/gold and white patterns underneath. The larvae of these flies are specialist parasitics on Hemipterans (true bugs)
