ThanksWow!First off that's an amazing photo!You nailed the lighting on that!
Some ant species I know fly when its kinda cold but I would almost expect it might be to late for most species right now??
How big is the queen?I'm not so great with ant ID's but it almost reminds me of maybe Lasius or Prenolepis?
Might have some good luck with ID here:

I think queen ants are just larger than workers and can be almost as mobile.I always thought ant queens were huge and immobile like termite queens. I guess I have seen many ant queens than in my yard!
