I would guess Camponotus modoc, it does not look to be shiny enough to be C. laevigatus.


Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies. 

However, I went back to the Sierras, and restarted my collection, which is now as follows:

Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).

If it has yellow hairs, it's definitely not C. laevigatus. I think it's probably C. modoc.

Camponotus pennslyvanicus.


That’s what I had been thinking all along but wanted to be 100% sure. The previous mentions above just don’t quite fit right. Here are a few more pics that might be a little clearer than the previous.

No. C. pennsylvanicus does not live in Colorado.  Well, according to antweb anyway.

Antweb is often incomplete. Use antmaps.

And according to antmaps they are? Well, I guess it would make sense, Colorado is in the rockies.

As I have said before ant maps also has its gaps and omissions, far better to actually learn how to identify these things rather than just throw out WAGs.

I believe we need clear pictures of pubescence to differentiate these black camponotus species.
