Queen ID for Central Indiana?

[Martialis]

She's about 10-20mm in length, black with red thorax, and I'm thinking C. Pennsylvanicus worker or Crematogaster queen. Here are some pictures of her: [Just ignore my profile, couldn't figure put how to post photos from my iPad ]

That's a Camponotus worker. I can't tell what species because the picture is dark. If you got a better picture, I could tell you the species.

Ya thiught so. I'll release her. She's not a C. Casteanus, I've seen those. She's most likely C. Pennsylvanicus. Thanks

A little hard to tell because of the picture quality but I'm almost positive it's C. penn, I live near Chicago and these ants are everywhere here.
