Andricus quercuscalifornicus
These wasps generally emerge from their galls in October. There are usually multiple wasps in one gall. (Some cynipid galls made by other species have only one wasp per gall; some have multiple wasps per gall.) These two wasps were probably very soon to emerge.

The host tree is Quercus garryana.
