After leaving Washington-on-the-Brazos State Historical Site, I made a few observations along the road through Washington, Fayette, and Lee Counties, none of which are in a Texas CNC metroplex.

Collected from a gall on Silphium asteriscus var. latifolium.
Gall was collected on 3 Oct 2023. Two Eurytoma sp. parasitoids emerged 25 Apr 2024. The gall and parasitoid adults were frozen (my incorrect assumption that they were inducers). I waited a week and fearing they were dead, and not wanting them to deteriorate, I opened the gall. I found eight adult inducers and five adult Eurytoma parasitoids. Additionally I found one larva that did not develop. All were dead but all of the adults appeared fully mature and several had begun tunneling out of the gall.

Host ID based on previous observations (https://www.inaturalist.org/observations/136309317) from same spot. Could even be the same plant, this is the only Lactuca I could find and looks like a 2 year old stem (galls vacated)

mossman13Descripción
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?).
