Bottlebrush Sawfly larva -molting

Pterygophorus cinctus


Pic #6 shows one of the instars of the bottlebrush sawfly larva between molts, holding its long tail up, threatened by my proximity. Pics 1 to 3 shows a newly molted larva with the skin hanging on to the long tail. Pics 4 & 5 are pictures of the larva after the molted skin dropped off.


Spotted on a Bottlebrush bush ( Callistemon sp)


Sawflies are neither flies nor wasps and their larvae look like caterpillars. Almost every branchlet and leaf had these larvae; the top of the bush was decimated by these sawfly larvae.
