Hello these are two ants I caught under the same rock right beside the river in Prince Island Park, Calgary Alberta Canada. Neither had any workers present. They are both just over an inch long. One is black but reflects bright gold off its legs and gaster with a slightly more pointed gaster.(Top) The other is a little shorter in length but also has a slight goldish tint to it with a slightly more rounded gaster and redish legs.(bottom) Any help to ID these pretty little girls would be much appreciated.
