The white thing, kinda hard but "fuzzy" exterior, about 3" long, wraps entirely around the branch. And those are two of the gazillion cicadas in my yard.

I just found some of these on one of my trees, also a white oak, and was amazed to figure out what they are. I had opened one and would have sworn there were seeds inside the fuzz, not insect pupae.
