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.

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?).

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.
