This photo shows the complicated channels inside the gall, besides the two central chambers of the gall causers. They indicate a rich community.
Inside this gall, apart from one newly-emerged adult Andricus quercuscalifornicus wasp, there were several tiny beetle larvae and a predatory stonefly larva.
For more about the parasitoid community of these galls, see this paper.
