Bottlebrush sawfly larvae Seen feeding on Callistemon citrinus. This grouping was on both sides of the leaf, you can just see the others poking up behind. I found it interesting that the two sets on either side had remained in sync, reducing the leaf at equal speeds. <br />

Body length 10 mm<br />

This is specifically the bottlebrush sawfly, Pterygophorus cinctus.<br />
<br />
Despite the common name, sawflies are not flies. They sit within order Hymenoptera, but within a separate suborder to wasps/ants/bees, namely Symphyta.<br />
<br />
Sawflies do not possess the distinctive thin waist of the other hymenopterans, nor do they possess a sting. The common name comes from the female&#039;s saw-like egg-laying tube, which she uses to make a slit in a plant leaf or stem, into which she lays her eggs. <br />
<br />
Our Australian sawfly larvae feed mainly on native trees and shrubs, such as eucalypts, paperbarks and bottlebrushes (although a small number of species are parasitic).<br />
<br />
15 mm body length.<br />
