c7609. This must be bivoltine, given how late in the season it is. I don't think it is likely it survived so green this long since the Spring.

Starry rosinweed? This one had leaves in whorls of four instead of three. It probably was introduced in this location by planting/sowing though I'm not sure how long ago and if this plant came up on its own. Not sure if this was still budding or already fruiting.

Silphium speciosum - midrib blister https://www.gallformers.org/gall/5439
Finally found one! Dissection revealed a large larval cell, but no inducer :(

1000’s of plants at this truly bizarre site. The Silphium seems to be all that is left of what must have been a large prairie, which was gouged and bisected by Rt. 19 in the last ~25 years. There are scattered native species accompanying it, but aside from the junipers, the most abundant here is non-native and invasive species. Although the parts of Bracken County that are not wetland and river-adjacent are under-botanized, it is a bit mind boggling that this population (and the natural community that went with it) went unnoticed by collectors in the past.

Thanks @alex_abair for your (quick!) feedback on observation https://www.inaturalist.org/observations/227662948.
I went back to take a few green balls, and open 2. Pictures show what was found.
Videos at https://youtu.be/JBFd6UiQw4E?feature=shared
and https://youtu.be/JR4R8Z9CCJ0?feature=shared
So we have (developing?) galls, @louisnastasi. Your info @friesen5000.
Remember: all with cheap clip-on macro lens attached to cell camera.

Photos 1 and 2 are wasp 1.
Photos 3 to 6 are wasp 2.
Photos 7 and 8 are wasp 3.
But it could also be 1 or 2 wasps that changes spot.
Same garden as usual, still no signs of galls (unless I don't know what to look for).

Same location, same host as observed the day before: https://www.inaturalist.org/observations/220788455
Can’t tell if it is the same specimen, so new observation.

On Q. falcata. Wasp on leaf w/ (probably) Polystepha galls. Sending wasp and leaf to Forbes lab. I thought wasp was recently dead b/c not moving but it moved when I tried to pick it up with tweezers. Put into EtOH.

Gall on Fumaria c.f officinalis. Inside I only found what seems to be a puparium. Thought it was empty until I observed this failed pupa shortly after.

I think this might be the sexgen of Neuroterus tantulus, I’ll try barcoding it to verify
