Succulent Oak Gall, Revisited

 
Two years ago, you might remember that there were thousands, probably millions, of these little balls on the ground under oak trees. After some research, I learned that they are succulent oak galls, caused by being punctured by a cynipid wasp. The leaf grows a ball of unusual cells around the irritation, where the wasp has laid an egg. Thus the egg has a nice safe home in which to develop.

Two years ago, almost all the galls had fallen to the ground. Yesterday, I found some still attached to a white oak leaf. And this picture shows the color variety better too.

Is there symbiosis? I mean, I see what the wasp gets out of it, but what is the benefit to the oak?

vanilla- nothing. Not really symbiotic, more parasitic

I used to see succulent oak gall on the leaves of the oak trees that surrounded our former home.
