I think this is some kind of desert Formica but I could be wrong. I found two that were alone, but then I found these two together under a rock, so it appears maybe they're polygynous? Found in Emery county, Utah hiding under rocks. Any ideas on species?

Ah ok! I haven't really caught either of these genus yet. The day I ID a Formica correctly will be quite the day. haha

I am surprised to see they were nesting together, as Lasius is not normally considered polygynous; that's pretty cool.

 Why keep ants that aren't found in your yard?

There are so many fascinating ants right were you live!

I disagree with the keeping/buying of ants that are not found in your area.

If they are Lasius Brevicornis then they can be polygynous. I think you need to look at their underside to ID them.

They don't look like L. brevicornis to me, but I could be wrong.

You may be right I don't think they live in deserts.

Edit: they can but less common there. Izzy I think you should try but it's entirely up to you

I think my big concern is just disturbing them at this point since I'm already test tubed them up and put them in a dark area. When workers arrive at some point would it be easier to identify based off of them?

Yes. If the workers are black then they are Niger group of they are yellow they are Brevicornis.

If they are Lasius Brevicornis they are one of my favorite speices.

That's cool! What is it about them that makes them one of your favorites?

I looked underneath one of them in the test tube that was standing above a clear part of the test tube (I have some dirt in there) and the underside seems to be much lighter than the top. So that makes me think they are indeed Lasius flavus based off these pictures. This lines up with the fact that I have the two that appear to be polygynous as well, so I think we solved it!
