Unidentified sawfly larvae on cottonwood and willow

Here's another note based on sorting unidentified sawfly larvae in the BG gallery by host plant, this time for cottonwood and willow, both in the willow family (Salicaceae).

Cottonwood (Populus deltoides), Maryland

Willow (Salix sp.), New York.

Willow (Salix sp.), Georgia (but see comment below).

As with my previous notes for other species (listing in "See Also" section), I am providing these sorted images in hopes that Dr. Dave Smith or other experts will find them useful, possibly leading to identifications.

Additions
I added four images of yellow sawfly larvae on willow to create a new bottom row for the display. I noticed that they resembled larvae that I had posted on my Oak compilation:

This prompts me to wonder if the "willow" might be willow oak (Quercus phellos), which also grows in swampy woods in the southeastern U.S. I will cross-list these images in the Oak compilation.
