About 3 cm wide. On such a short plant.
Not sure of host species, but touching plants seen on observation:

5/5: a whole bunch of Periclistus (https://www.inaturalist.org/observations/214329475)
On rose sp growing in true old growth prairie. Tons of galls, probably 20-30 in a 20 foot radius...Prairie Horizons remnant prairie
Emerged from rose stem galls collected here: https://www.inaturalist.org/observations/98753609 on 10/18/21. Preserved in vial 118. More expected to emerge.
On Rosa foliolosa. Collected 4 for rearing, but will go back to collect more.
On Rosa foliolosa
I can't make out which species this might be because there are several similar looking twig galls.
Had a spectacular morning at the Benbrook Lake Richardson Tract Prairie Bioblitz -- perfect weather and this piece of land is incredibly rich with biodiversity. Spotted a bunch today! :)
This is for the adult which emerged on this date from galls collected on 4 Sep 2022.
On Rosa gymnocarpa, glad they stuck around for Gall Week!
Aren’t they wild? @mileszhang @stephaniesq @laszlozoltan Earlier in the year they were normal red puffy things with short to medium sized spines. Coalmine Ridge.

Finally got a chance to revisit the site of https://www.inaturalist.org/observations/143630146 and sampled another three galls. Figuring they'd all be empty already, I sectioned one in the field and lucked out on a live adult female! Large, intact specimen with tons of golden setae, beautiful. Leaning Q. macrocarpa on the host for all three, probably the original find as well.
Been digging around on Gallformers trying to find something similar and the closest I've gotten is Cynips heldae (https://www.gallformers.org/gall/1368) - but the host/range/gall location don't match. Very similar structure, though.
But wow what long spines! On Baldhip Rose. Coalmine Ridge.
Host:Wild Rose. Spines sparse, short, and meaty compared to most galls of this type that I've encountered.
Check out the GALLS on this purple prairie clover 🤣
Midge larvae dissected out of Dalea purpurea flowers - probably undescribed?
On Rosa sp.
According to this observation, this is part of a known group of Diplolepis that are not quite consistent with D. polita. I will keep this at genus level until molecular work clarifies the relationship, unless it would make more sense to assign this to D. polita in order to atlas this group for subsequent taxon swaps
Maybe? Or not a gall despite the odd shape? Several of these, on wild rose (tentatively Ground Rose - Rosa spithamia) with some D. polita nearby
