large amounts of workers & queens. As my wife was calling to me to come to dinner 
, I grabbed my camera, got down on the ground and took some shots. The first hole I noticed only had males coming out and about 6" away in the grass was another hole with a mass of queens and workers. Another interesting thing I noticed is the fact that their are two different workers tending the males and females. After a few moments, the males started showing up were the queens were emerging (those pictures did not come out good enough). Looking through the bugguide, I came up with the species Lasius and doing a little more searching, it seems that some species (a queen) can enter a nest and kill the other species queen and take over the nest. You have a mixed nest for a while until the workers from the other species die off. This is called "Temporary social parasitism". I may be way off the wall here because I am no expert on anything. This could be two different species!! Even if i`m wrong, I would never have known about Temporary social parasitism at all, if I had not dug a little deeper into the info.This is the picture of the males
These are the queens
. Great find.
Here`s a little more info on the subject;
