Panzner Wetland Field E in restored emergent wetland (SE corner, only one I saw). This keys out to either lupuliniformis or or lupulina, but am not sure whether the edges on the aches have a prominent enough knob to be the former. I included a second photo with a closeup (iphone through microscope eyepiece) of an achene, hoping someone with more experience can tell which.
My impression of the plant in the field was that it looked different than the Lupulina I've seen before - perigynia point more forward, I think, coarser.
Panzner Field B at ground level. Uncooperative seedling prevents a good view of the eyes, but didn't want to disturb him

Four poults at roadside along Center Road.
Lit in pines on SE corner of lot. First on property.
4 individuals, 2 adult, 2 young. Youngsters are almost full grown now! Difficult to tell them apart from the adults except that the adults are still protecting them. I got too close while walking to my car, one did a divebomb and the other adult did a wing drag.
described in Ohio Crayfish and Shrimp Atlas as "Cambarus species A"
