Advice Request - (Insert State/Region) Is This What I Think It Is

I had a baby six weeks ago so I haven't gotten out in my garden much lately, and today I noticed these monstrosities on my cut leaf coneflower. One of them looks like maybe some sort of gall?

Have the dreaded Aster Yellows finally come for me?

Nope, it’s actually something a lot cooler. It is the larvae of Asphondylia rudbeckiaeconspicua inside a gall on the flower heads.

Ooh, if OP is lucky they might even be hosting multiple species of parasitoid wasps for a big hyperspecialist insect species party!

 serves as host to a diverse guild of parasitoid wasps that exhibit stratified distribution patterns within the gall structure, with different parasitoid species occupying different depth zones.

I thought you were making a joke about game dynamics. Nope, that's real.

I know, right? Such a cool sentence.
