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.

I can just make out the tiny yellow-orange spot and additional yellow-orange marking on the abdomen behind the hind femur, as well as the yellow-orange marking on the tip of the abdomen. Both of these markings as well as the yellow on the top/side of the pronotum and white femur make me think this could be a female Lophyrotoma leachii. I might get @Jimbobo to have a look for you though😊
