It is a queen. Lasius sp. I believe. Maybe Lasius brunneus but I'm really not sure.

That looks like Solenopsis invicta but the picture is not very clear. Also, when making a post to identify a queen please consult this page: https://forum.AntsCanada.com/viewtopic.php?f=48&t=292 Thanks

I believe that is a large worker and not a queen. Probably Camponotus sp.

It can be difficult to tell, but Formica queens are generally significantly larger. Also, Lasius workers are generally quite small compared to the queens. Formica workers and queens are more similarly sized. This isn't a very scientific distinction, but you can also use color as a determining factor...

I'm pretty sure that's a Florida Carpenter Ant, Camponotus floridanus. Good find!

The queen does appear to be Tapinoma. Usually when queen ants lay eggs sporadically and don't really care for them it means that the queen was not fertilized. This is quite common.

Sorry for the very late reply, but I really don't think it's Camponotus modoc. Modoc's range extends east to only about Minnesota. I'm quite confident it's Camponotus Pennsylvanicus or maybe Camponotus nearcticus but I doubt it's the latter. The leg coloration is a bit odd though, maybe someone else...

Here's a list of known Alaskan ants: https://www.antweb.org/taxonomicPage.do?rank=species&adm1Name=Alaska&countryName=United%20States Only 5 genera appear on the list: Camponotus, Formica, Lasius, Leptothorax, and Myrmica. I"m going to guess a few other Camponotus species not listed on the website (...

First queen is certainly Solonopsis invicta, second is Camponotus sp. most likely Camponotus pennsylvanicus. As for the queens found near one another, Solonopsis queens sometimes found their colonies together, although I think it was most likely a coincidence that they were nesting so close to one a...

Lasius sp. Individual Lasius species can be hard to identify by the queens alone. You might have to wait until workers arrive for a more accurate I.D.
