Pavement Ant Identification (Two Node Ant)
Pavement Ant (Tetramorium caespitum)
Description of Workers: Small workers, around 1/8-inch (2.5 to 3 mm); light to dark brown or blackish. The head and thorax is furrowed by parallel lines. These ants have one pair of spines on the thorax and a sting on the tip of the abdomen.
Pavement ants get their name because they often nest under sidewalks, driveways and building foundations. A mound of displaced soil along a paved area is probably a sign of pavement ant activity. During the winter, pavement ants may nest inside structures near a heat source.
