Sawflies (Hymenoptera, Symphyta)
Sawflies are wasp-like insects that are in the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs.
The primary distinction between sawflies and the Apocrita (ants, bees, and wasps) is that the adults lack a "wasp waist", and instead have a broad connection between the abdomen and the thorax.

Thanks very much Jimbobo - will do later tonight! Yes, it's a sparsely vegetated hill.

1st image has a female Pseudoperga ferruginea on the left next to a male Pseudoperga guerinii. 2nd image is a female Xyloperga amenaida. 3rd image is a male Pergagrapta bella. It's a great record showing a strong hilltopping behaviour in Perginae species. I assume it's a sparsely vegetated rise, leading to a concentration of insects. If you split the obs out then they can be separately identified.
