Host plant?
Unless you observed the larva feeding on sensitive fern, I think it probably isn't Hemitaxonus dubitatus. See discussion here. And here, just for example, is an instance of a turtlehead-feeding sawfly larva that just happened to be found on a sensitive fern.

re: Host Plant?
I didn't see it eating the Onoclea, altho' there were few other plants in the area. I was probably influenced by this image

That does seem like Onoclea...
Dr. Smith has said that the larvae are only known for about 1/4 of North American sawfly species, so it's always possible that it's some other species. It would be interesting to try to rear these if you find them again--I don't think I've seen one, but I'll keep an eye out.
