Awesome!

I've always wondered what sawfly larvae look like without the wax on them :)

Awesome hey

Thanks for the comment. There seems to be a narrow window between stages. I guess I got lucky.

Did you watch it more after that?

If you did, did it start exuding new wax right away? I've always been curious about the process certain insects go through while building this waxy covering. It'd be awesome to see it. I don't know why but I was expecting them to look different than sawflies that don't build up wax.

Yes

The next day after shedding they were all stretched out and moving slowly toward the stem of the small tree which was completely bare. They were still very smooth. The day after that there was no sign of them save the shed shells.

very interesting! - any pics of that?

There are some lady beetle larvae with similar waxy white filaments, and I've always wanted to see them molt and develop the new covering. Never manage to catch them at it, though, and they're tough to rear in captivity.

No

No I did not take in photos the last day. There did not seem to be any noticeable change.
