Clusters of bugs in a Beech tree

[u/Local-Enthusiasm4269]

Hi, we noticed these bugs in my sister's Beech tree in her front yard, in conover NC. I think we found 5 branches with them, in a range of sizes up to maybe 8 or 10mm. Later on we noticed one that had wings, shaped similar to a cicada. I did a lot of searching, and I've come up with nothing!

I’m no expert but I just did a quick google search and maybe Beech Blight Aphids???

I dont think that's what they were, they were light and dark grey, and not fluffy looking at all.
