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. Workers do have a small stinger, which can cause mild discomfort in humans but is essentially harmless. Alates, or new queen ants and drones, have wings, and are at least twice as large as the workers.
The drone’s only job is to mate with the virgin alates, and reproduction is at its highest in spring and summer. The dealate, or newly fertilized alate, finds a suitable nesting location and digs a founding chamber called the clausteral chamber/cell. As the eggs hatch and the ants develop, they 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 other insects, seeds, honeydew, honey, bread, meats, nuts, ice cream and cheese.
