Large ant - Camponotus vicinus
Copyright © 2010 Heidi Eaton

Large ant - Camponotus vicinus
Northwest of Cañon City, Fremont County, Colorado, USA
April 5, 2010
Size: ~13mm
This large ant was on a tree, but not sure if that is significant or not. The size did remind me of carpenter ants, but I didn't see any in the guide with black head, red thorax, and black abdomen.

I think this is Camponotus vicinus
A widespread Western and mid-Western species whose color pattern varies according to the region: head is black on the Pacific Coast and in the Rockies, red in the Great Plains. At least the distinctly flattened femora indicate subgenus Tanaemyrmex, to which C. vicinus belongs.

Thank you!
I'll move it to subgenus.

There are at least a couple of species
with that general pattern:

and

Unfortunately, neither of these seems to occur in your area.

Which, now that I think about it, really isn't very helpful, is it? Okay, just forget that I said anything. :)

Thanks anyway :-)
The one in the first image looks especially like mine, but it does seem out of range, although apparently they range to Alberta, so maybe...
