Pine Cone Oak Gall - Andricus quercusstrobilanus

Pine Cone Oak Gall - Andricus quercusstrobilanus
Newburyport/Joppa Flats Education Center, Essex County, Massachusetts, USA
August 24, 2018
The gall is on Swamp White Oak. A very similar image at the Missouri Botanical Garden labels it as Pine cone oak gall (Andricus quercusstrobilanus). I haven't yet found images of the wasp involved, so should I use dissection to see what is inside and photograph it, and should I keep one or more of the nodules in a jar until the adult emerges?

Sorry you didn't get a reply sooner... a photo of the adult wasp would be more valuable than a photo of a larva. Offhand I'm not sure if adults should have emerged last year or would need to overwinter in the galls.
