Abundant in patch of Silphium terebinthenaceum in ~30 yr-old tallgrass prairie restoration. Collected 3 individuals from 3 stems on 6/9/22 and 6/10/22. Reared in potato and carrot. Pupated on 8/15, two on 8/21. Eclosed respectively on 9/11, 9/24, and 10/03. All P. silphii. Subsequently released. All captive observations marked casual but can be found in the observation group field from those larval observations. Reared from S. laciniatum from this site as well this year.

same gall from a previous observation (should add link later, maybe I will). Is this wasp returning to a gall it made? If so, why? It doesn't look like it's emerging. Is it interacting with the gall of another insect- parasitizing it, maybe? I don't know a lot about cynipoid behavior- any insight is welcome!

Q. rubra
Initially collected as a C. rubida specimen. Dissection of several galls revealed chambers absolutely packed with larvae - possible inquilines? Tentatively identified as Ceroptresini by @moneykittens. Larvae preserved in 95% etOH, attempting to rear adult specimens.

Galls collected 11/5/2017; this is what they looked like in summer 2018 when the adults emerged. On Quercus ilicifolia.

Found on Lindley's Silverpuffs on 9/4/23. No one has been emerging @louisnastasi so I decided to dissect one yesterday in the "lab." (Based on a comment you made) Not much seems to be alive?

There are patches of fading Microseris douglasii at Pulgas that could be checked for Microseris galls.

This observation is for the galls in the stem. I’ve collected a couple of these so I can see what emerges.

I thought this was dried seeds but I broke one open and there’s just a hole inside. Wasp galls.

awblair描述
These were all past flowering. Another example of the tall form of entire-leaved Silphium with ~dense leaves all the way up the stem that are found in riparian/floodplain habitats in the Hill Country. In the past, I had called these S. asteriscus though I honestly have no idea now. They are quite distinct from the upland forms I've seen in the Hill Country (S. gracile?) and those growing in sandier soils on the coastal plain (S. radula?).

On Silphum.
Update: Emerged within the past day or so, I checked 25 Apr 2024 and there was at least one exit hole and one alive adult.

What's going on here? Potential hybrid of S. laciniatum and S. perfoliatum, or just strange S. perfoliatum? Very deeply cleft leaves that are not connate. Lower cauline leaves only slightly clasping with long petioles. The stems are square at the base and round more than 18" above the ground, and pubescent where square only. The one stem with lower leaves alternate instead of opposite has a round stem throughout. The underside of the midvein is pubescent. The second to last picture is me holding a flower of nearby S. perfoliatum (left) and S. laciniatum (right) against this plant's flower (top), showing the larger size.

S. laciniatum and S. perfoliatum hybrid or just weird S. perfoliatum? Further notes in @trevorzook 's description.
Last photo with three flowers in the hand compare nearby S. perfoliatum (bottom right) with S. laciniatum (top right) and the plant in question (left)

Alternate leaves; basal leaves rounded/cuneate- not cordate; ray flowers showing 11 on photo but likely one missing; other similar Silphiums have opposite or whorled leaves. S. Radula is west of the Mississippi River

Found another area with hundreds of galls- maybe more! On Lindley’s Silverpuffs.
