1. Location: In some rotted siding boards near the top of my house.

2. Date of Collection: 7/5/17, though I'm sure they've been there a while.

3. Habitat: Construction Lumber

4. Length: 3/8"

5. Coloration: Black, but the pronotum of the thorax is red. At least in one major worker I collected, it's orangish-yellow.

6. Distinguishing characteristics: N/A

7. They weren't aggressive, and did a very poor job of defending their colony. It was a relatively small colony, 100-200 workers? Lots of brood. I don't see a queen anywhere.

8. Rotted lumber.

9. Best pictures I could get of one of the workers: http://imgur.com/a/che2Z

Location means like your geographic location.

"Rotted siding boards near top of house" would fit under habitat.

Chicago area, I believe.

 

Those look somewhat like Camponotus subbarbatus to me.

This looks like a Camponotus major worker. Once again, geographic location would be essential to identify this ant down to the species level.

Do you need more precise location information than my county?

I completely forgot about the location in the title! My bad!

 

I think this ant is either Camponotus novaeboracensis or Camponotus herculeanus.

I would go with a Camponotus major from the Myrmentoma subgenus due to the size. Martialis, the C. subbarbatus - looking striping looks like it could be just a full gaster.

It's nearly half an inch, that's not too small. If it's in the Myrmentoma subgenus, I would go with Camponotus nearticus. C. subbarbatus would have much more noticeable stripes on its gaster and C. caryae would be uniformly black.

C. nearcticus have mesosomas that vary from red to black.
