We said earlier that this sawfly larva was on dogwood, but when it didn't look like the dogwood sawflies in the guide, we decided to go back and check our plant identification. Good thing, because it turned out to be feeding on buttonbush, Cephalanthus occidentalis. We'll correct our earlier post.

Moved from Pseudosiobla.

Thanks for the ID!
I'm curious for your thoughts on the other images collected here. They were placed in Pseudosiobla based solely on host plant, so it's great to get confirmation. How does P. cephalanthi differ?
