Pavement ants or Slab ants
The pavement ant is dark brown to blackish, and 2.5–4 mm long. Like other ants there are the workers, alates, and a queen. Alates, or new queen ants and drones, have wings, and are twice as large as the workers. The drone’s only job is to mate with the queen, and reproduction is at its highest in spring and summer. Tetramorium, like many other ants have nuptial flights where drones fly high up in the air and mate with new queens.
The queen finds a suitable nesting location and digs a founding chamber. As the eggs hatch and the ants develop they will spend that time, about two to three months, tending to the queen of their colony. They will continue helping in the colony until they are a month old. Older workers hunt and defend the colony. They will eat almost anything, including insects, seeds, honeydew, honey, bread, meats, nuts, ice cream and cheese. The species does not pose a public health risk, but can contaminate food and should be avoided.
