Marble galls are caused by the larvae of gall wasps (Andricus kollari) which lay their eggs on oak buds. The hole is where the wasp emerged.

This is very interesting and not something I had known. Love the informative posts and wonderful photos.

Very interesting, if compare to the buds that are found besides the Marble Gall.

I agree with everyone else, it is very interesting. I always wondered what kinds of things would cause a gall. Wasps make a lot of sense.
