I’ve never sliced open an oak apple gall but the North Park walkers did while Dianne Machesney took photographs.

It was red and juicy inside.  Hmmm!

We don’t know which bug made this gall and the bug died in the slicing so …

Can any of you identify this gall and the insect that made it? It was found in North Park, Allegheny County, Pennsylvania in mid August.
