I recently found a very similar sawfly larva, shown here, and it was suggested that it resembled a picture of yours found here. After looking around on bugguide a little more, I found this, which is identified as Hemitaxonus dubitatus based on feeding habits. There's also another one of your images, identified as Selandriinae. It seems you've been unwittingly taking a lot of pictures of these guys!

I'm not sure how diverse the Selandriinae larvae are, but these all look very similar, if not quite identical, to my relatively untrained eye. Hopefully someone with more expertise can help us out, though.

It looks like this is one of the Selandriinae, and I don't really know about their diversity either. Dave Smith is our expert on sawflies, so I usually wait for his opinion before moving them.
