In Quercus agrifolia acorn, larvae/adult ~3mm across.

4 entry holes found in acorn cap, 7 larvae found in pericarp by cutting acorn sequentially in halves.

Only one moving slowly, (others not developed enough to move?)

Preserved all larvae in 40% ethanol and refrigerated.

Keeping this observation as a record, but it can't be improved past Proctotrupomorpha since 2 organisms are being depicted, the original gall wasp C. eldoradensis, and a Chalcicoid parasitoid wasp that later consumed them.
