Interesting! I'll have to start checking rolled beech leaves for sawflies.

Thanks for the list!
I do not have more information at present (except that Acantholyda erythrocephala feeds on Pinus spp.), but I copied your list here so it will be easy to find again!

(I did not check coniferous species)

I do not understand how you k
I do not understand how you know the plant?

 
Plant photos removed
Some BugGuide editors don't like having the website cluttered with photos of plants, so they remove them after the plant has been identified. I assume that's what happened in this case.

 
Thank you!
It is subfamily Pamphiliinae because the depression (dented area) in the middle of the anal segment is not triangular. Triangular dent in subfamily Cephalciinae (Acantholyda and Cephalcia).
But, unfortunately, I could not find any species associated with these plants.

Fagus grandifolia
The host plant is definitely beech.
