Unidentified sawfly larvae on oak

Here's another note based on sorting unidentified sawfly larvae in the BG gallery by host plant, this time oak (Quercus).

Massachusetts. Photos taken in same vicinity by same photographer two years apart.
Masschusetts and Virginia. Host plant tentatively identified as oak in both photos.
Virginia.
Ohio. I noticed that this resembled an unidentified sawfly larva that I placed in my Birch compilation:


As with my 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.

Caliroa spp.
It's worth noting here that several Caliroa spp. feed on oak leaves. They are common and there are obvious differences among the larvae of at least some of the different kinds, yet Dr. Smith states here that no one knows which larva goes with which species. The only oak-feeding Caliroa we have identified to species is one MJ Hatfield reared this year--I hope others will follow suit!

Possible willow oak
While adding images to the Willow compilation and noticing that they resembled the topmost images posted here in the Oak compilation, I wondered if the host plant might be willow oak (Quercus phellos), a southeastern tree with remarkably willow-like leaves. Accordingly, I am cross-posting them here:
All four from Georgia.
