Oak Gall Wasp (tentatively Feron sp.) collected as a gall on Engelmann Oak on 2/18/23 at Santa Ysabel Preserve by @madily. See discussion here: https://www.inaturalist.org/observations/149459575
Two batches of photos:
1) Live adult photos are of the live wasp, taken through the Ziploc plastic and then photoshopped. Too afraid I'll lose it if I do anything else for now.
2) Wasp died in the Ziploc 3/5/2023. Dead adult photos taken with Olympus TG-6 and added to this observation the same day. Will ship specimen to @megachile for better photography.
Possibilities: In the bag @madily gave me to deliver to the Norcal oak gall fans, I have two Englemanns twigs. The first has a single 'Feron' gall, which is still attached to the underside of its leaf and appears to have an exit hole at the top (which may have been there already, eg, an empty gall). The second twig has a leaf with both an Andricus reticulatus and a Feron gall, next to each other. This was iNatted en situ: https://www.inaturalist.org/observations/149766861 That Feron gall has since fallen off the leaf and does not appear to have an exit hole. The Andricus reticulatus gall does have an exit hole now, but that may have been there before.
Therefore... this adult could be 1) the Feron sp. inducer, 2) a parasitoid wasp; or 3) or Andricus reticulatus. Or something else that hitchhiked on the twigs, but that seems unlikely. There may be other possibilities as well!
A non-exhaustive search for online photos of adult Andricus reticulatus came up empty. Does anyone have one?

On Mentzelia involucrata. Not certain on the ID, but the limited information on Mentzelia stem galls implicates a Cecidomyiid.

Host: Serviceberry. Russo (2006), in Plant Galls of CA, pg. 324, discusses several undescribed species in this genus, some of which were discovered while preparing his first field guide in 2004. In his 2021 updated field guide, pgs. 316-317, it becomes apparent that this gall maker must be his "Red-Lip-Gall Midge", or Blaesodiplosis sp. E, although it is much more densely distributed on the leaves than in the photographed example.
This observation originally misidentified the host plant as Common Snowberry.

Possibly Russo's 'Basket Gall Wasp' (Unknown #6) on Blue Oak. See Russo (2021), pg. 127. Russo describes this as occurring only on Blue Oaks and known only from the Redding CA area perhaps 100 miles NW from here, and as occurring only on dorsal surfaces. These were present more or less equally on both dorsal and ventral leaf surfaces.
