I caught 10 of these queens sometime last fall, I think around September/October. At first I thought they were Lasius Neoniger, but now that the workers have eclosed they are a nice yellow color and definitely are not Neoniger. I'm thinking maybe Flavus or Nearcticus. Apparently they mainly farm aphids, so at some point I may need to try to figure out how to create a setup with them but for now they seem to love honey and this colony seems like it's accepted a fruit fly.
Another interesting thing is that when I caught them, they were in clusters of 2-3 queens so I'm guessing they are polygnous as well.
