I did some searching and I'm thinking it may be Hypercompe scribonia

What do y'all think?

Well I know nothing so take my opinion lightly but I think you are right, it looks very much like the picture in "Caterpillars of Eastern North America".

Yes, it is a great leopard moth (Hypercombe scribonia). The red bands show when curled up and advertise that it is full of PAs (pyrrolizidine alkaloids), a toxic substance. Your guy is probably getting ready to pupate. Typically they overwinter, so I don't know if yours is just hanging out or what. It may be a first brood, with a second overwintering. I find them hard to raise, as they pupate in the leaf litter, but someone else on the board my have some advice.
Good luck,

I got it some willow leaves, as that was about the only thing I have in the yard that was on the list of host plants, and it was sort of active for a while. Then it left behind a large piece of frass and is now rather quiet. I can give it leaf litter (I don't have everything raked up even into July.) Normally we don't have cold weather for several more months--November, typically--so I'm wondering if it's really set to overwinter?

I fed a Great Leopard Moth Common Plantain once. I kept the Plantain a live inside. The moth ended up using its spines to make a cocoon. It did winter over and I did get to see the adult stage.

Went down to the West Jefferson, Ohio McDonalds last Wednesday night. My son caught a giant leopard moth. I love the blue on their wings and body.
