On Blue Oak. Has no summer all-female gall been seen yet @megachile @norikonbu ?
On Blue Oak. @norikonbu No Striped Volcanos to compare on this tree, but these Neuroterus fragilis are definitely solid. Looks like they flew the coop too.
On Blue Oak. Spring Striped Volcanos here too @megachile?

Empty Q. palmeri galls collected 2/17/24 from FONM. Uploading for morphology and maybe age/color of galls can tell us when they're good candidates for live galls to reduce collection impact.
Uploaded in reverse order by iNat uploader, each picture of an intact gall by ruler represents a different gall.
2nd photo (reordered from #7 to increase visibility) might actually be a thorax or abdomen?

Reared from leaf gall, not catkins, of Quercus agrifolia (Coast Live Oak). Plant material (see photo #5) collected April 10, 2024, photographed in 70% isopropanol on April 12th, 2024. April 12, 2024. The wings were fully inflated so it could have emerged any time April 10, 11, or 12, 2024.
Reared from leaf gall, not catkins, of Quercus agrifolia (Coast Live Oak). Plant material (see photo #7) collected April 10, 2024, photographed live April 12, 2024. I believe the wings were still inflating so most likely emerged April 12, 2024.
Collected 4/10, emerged 4/12. Sexgen galls. Last photo is exit hole.
Many individuals ovipositing on Quercus garryana buds.
