I found this queen July 9, 2015 at around 5 o'clock in Sioux Falls, SD. I believe it is Lasius alienus, just trying to confirm that. I currently don't have any means to measure, so I can't get measurements... Her gaster is quite long, and she has the customary yellow tint on her legs of L. alienus.

 

sorry for the blurry pics

It is either Lasius flavus [too early I feel] or something completely different then lasius maybe even Dorymyrmex?

 

Could it be Lasius niger?

Dermy: I strongly believe that she is Lasius alienus as they are flying now, but Lasius flavus could be right...

 

Here is a better picture of her. And boom she laid an egg!

If she has yellow legs and bottom (whch looks like she does on the photo), it's Lasius flavus.

What about other yellow Lasius spp.? How can you tell if it's L.aliensus or L.flavus and not a different species, anyways I don't think it's L.aliensus.

I believe this is Lasius alienus.

He clearly stated that this might be either Lasius alienus or Lasius flavus, so I wrote how to distinguish between them. Lasius alienus doesn't have a yellow bottom, while Lasius flavus does. Of course it might be other Lasius spp. species, but I just wrote how to tell the difference between mentioned two :)

Oh, ok. Sorry. Still don't think it's L. aliensus. Mainly because it's legs are really yellow in the picture.

All of the Lasius alienus in my area have really yellow legs and they are black... I guess it could be a different ant.

That's cool. The ones here have brown legs and are dark brown.

The Lasius alienus and Lasius flavus species that you are used to in Europe are not necessarily the same species as we have here in North America. Those characteristics don't necessarily apply like you think they do.

Alright, I'm sorry if I caused some trouble. I didn't know we had different subspecies of these.

That's fine, just something to keep in mind for us North Americans.

I am now not sure. I will need some measurements, but I think it might be Lasius pallitarsis

She also has lots of yellow underneath her gaster.

I found these pictures of a queen that is almost the exact queen I have. From gaster color, to size, to antanea color. It is most likely this ant. Unfortunately it is unidentified...
