I collected this gall from a Coast Live Oak in October of 2021. I kept it in a container with the end of the branch in a little bit of water that I changed weekly. On January 21 2022 when I opened it to change the water, I found a hole in the gall and the wasp shown.

Dozens of identical-looking adult gall wasps crawling on Dryocosmus dubiosus galls, some with exit holes. Galls present on this same Coast Live Oak include (tentative IDS): Aceria mackiei, Dasineura silvestrii, and lots of Dryocosmus dubiosus.

This observation is for the adult wasps; could be newly-emerging Dryocosmus dubiosus, or they could be another species, perhaps parasitic.

On coast live oak. I think these are galls - but I suppose they could be new growth. [edit: they are in fact galls]. However, they don't look like buds I'm familiar with, and I only found these on one tree [edit: after multiple re-visits, I found these on two trees]. This tree had a couple old Amphibolips quercuspomiformis, but the spring form of that gall is entirely different than this.

See https://www.inaturalist.org/observations/148539708 for what may be old forms of this gall, found nearby on the same tree.

See https://www.inaturalist.org/observations/148848266 for dissected gall

Stem galls found on trees that also had the n-densiflorus-tanoak-fuzzy-gall on leaves. Pulling both apart revealed identical gall structures and identical larvae. The larval chambers seemed typical for a lot of midge galls, being small "pockets" in the gall tissue which aren't actually sealed shut, and can be easily opened along the seam.

A third leafy gall found on Grindelia sp.! I split this one carefully open with my fingernail to find a perfect little chamber in the center of the leafy gall filled with ~10 small translucent larva! When I was done photographing, I smushed the two halves back together because the sap is so sticky and left the gall on the plant.

Russo's "Flange Gall" (2021, p128). On Q. douglasii. Most of these seem early stage to me, without the points at the base. This is the earliest I've seen any of the galls; previous observations were in Aug, Sep, and Oct. There is an insect next to the oldest gall. I can't tell what it is (no great photos), but I put together the "best" shots in the third photo.

I was surprised to notice what appeared to be several fresh galls of varying growth patterns on my backyard Frangula californica.

Part of my surprise is the timing. It is early for flowering and especially fruiting. When I looked at the bush today I only found one flower bud on a bush that is approximately 2 meters x 2 meters. Yet there were 7 apparent galls of varying forms. I am moderately-to-highly confident that these galls did not exist in November.

This gall looks a bit like a possible fruit gall previously reported here:

https://www.inaturalist.org/observations/95882473

But it is lacking the pointy appendage (which was visible on some other galls today).

It looks like there was a single puparium (or is it two?) inside.

This is distinct from the spring flower gall that has multiple larvae inside, as seen here:
