I caught these queen in an absolutely enormous nuptial where the alates in the air were partially blocking out the sun! As soon as a male attaches to a queen in mid air, the queen slowly flys to the ground. I missed a lot of it, due to the fact that I was in my bed with the AC cranked up, trying to cool a fever. I ended up with four queens. The colonies of this species are huge. Right outside the door of our RV, a colony swarmed up a rock, making it black, and the stump next to it. It was like a fountain of alates! I followed some queens with males until they hit the ground. I also found a dealate walking around near the massive nest. I assumed she just landed there. Hopefully these survive hibernation, as we are camping in the
Eastern Sierras, where there is still some snow on the mountains.
I think that this could be the Lasius nr. niger which seems to be only found in the Sierras. I would make sense, as the workers are fairly large, almost black, and have gigantic colonies. They also look very similar to Alex Wild's picture of them.
