Some kind of scarab. (Or perhaps stag beetle? The location and habitat makes me think Lucanus or Dorcus, but the shape and posture seems off.) Looks an awful lot like Cotinis but I don't know if those range into Wisconsin. Polyphylla maybe?

Yeah, there is alot of possibilities. He brought it to me yesterday, shortly after I made this post. I will try to raise and see what it is. However having limited knowledge on such things, I think it will be rather difficult.

I think I will go with beetle, but place it back into rotten wood and let us know if it works out.

Salmon has it pretty specific. It is not a Lucanid because they live underground. I would guess a large scarab possibly a grapevine beetle, june beetle or some other large scarab from the size. As Salmon said possibly a Polphylla. Possibly Osmoderma eremicola.
Hope this helps,
Tim

Osmoderma eremicolla because you found it in a rotting tree, doubly so if the tree was still standing. Cotinis and Pelidnota both are more likely to be found in other rotting debris, especially something with a lot of rotting leaves or where there's plenty of dung or compost.

I think your right with Osmoderma eremicolla They are fairly common beetles here in the summer, and the location seems right. If it lives, we will see. Currently I got it in a container with some moist decaying wood. I will have to do some research later on diet.

Don't most lucanids live in rotting wood? The habitat is what made me think it could be a lucanid to begin with. (Though it doesn't look like a lucanid, of course.)

Yes, you're right, but don't Lucanus capreolus live underground? I may be wrong. Maybe they are just eating the wood partially buried?

Would be nice to have a mate, from what little I have read they seem to be rare, but I would certainly like to see a few of these raised.
Looks like habitat destruction continues to kill off many beetle species.

I'm heading out to the woods this weekend. I will split some Logs and such, to see if I can find any more. Would be kind of cool if I could get a pair.
