A friend who knows I keep queens promised to bring me a, "real big queen." I didn't know if he'd be able to make good, but lo and behold, two days later he handed me a jar with a real giant of a Camponotus.
This is Specimen XVI:
Color: Mostly black and shiny. Legs and
Where: North Boulder, CO. Apartment interior or exterior (as I was told). ~5400ft. elevation.
Size: 17mm length, 20mm with wings included.
I shot some pics of her under red light, as well, as this messes with my camera's color balance and makes the red parts of ants show up as a translucent bluish color that contrasts well against black. You can see that the legs, mandibles, wings and petiole of XVI are the only places where there is any red to speak of. Here's one of those pics:
Doctorant explained on one of my other Camponotus queens' threads that the black Camponotus that live in Colorado are C. laevigatus and C. modoc, but I don't know if I am confident telling the two apart.
If I had to guess, I think it would be C. modoc.
