Ants of the Southwest: North American Army Ants

While there we encountered at least 3 species of army ant. Neivamyrmex rugulosus which was near the station. Neivamyrmex nigrescens which was farther up the mountain. And Neivamyrmex opacithorax which was the smallest of the three and found out in the desert at night. At least 4 males were found at black lights at night but identification of them requires dissection and examination of their reproductive parts. Colony fragments were later released. (And likely dumped on other ant colonies to test the evacuation theory.)
