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.

Identification based on Eucalyptus foodplant. Pterygophorinae larvae are as indistinguishable as Perginae larvae.
