California Scrub Oak; This gall was found last year by Merav Vonshak except it was purple; I assume it will turn purple with time; this was a cluster of at least 3, maybe 4 galls. Gallformers: q-dumosa-pip-gall

Looks like this is a parasitoid on Coyote Bush Bud Gall Midge, Rhopalomyia californica.

I'm just guessing on the species because Russo says that Platygaster californica is the most common parasitoid on the galls and photos I've seen are roughly the same. But I gather that there are a handful of others, some from different families like Torymidae and Pteromalidae.

The other photos show the twig and the wasp apparently ovipositing or getting ready to do that.
