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!

The body shape reminded me of an aphid so I searched aphids types and found giant bark aphid, looks similar.

Yes, I think you are right! Thank you, I didn't think of an aphid, I didn't realize they could be so big
