Observed this flight at 3am on 06/17/2013 in NE corner of Missouri. Temperatures are fairly warm and humid and it rained on 06/16/2013. It appears to be an all queen flight. No males spotted anywhere. The queens are approximately 1 half inch in length without having anything to measure them. The workers are about half that size. They appear to be solid black in color. Here are some photos I took with our digital camera. I have no idea what kind of ant this is. ID's are welcome. Polygamous or monogamous?
