Carpenter ants are large (.25 to 1 in or 0.64 to 2.5 cm) ants indigenous to many parts of the world. They prefer dead, damp wood in which to build nests. They do not consume it, however, unlike termites. The Ferruginous Carpenter Ant is also known as the Red Carpenter Ant.
Most of Eastern USA, excluding Florida and northern New England. C. chromaiodes occurs in remnant dry-mesic to mesic oak woodland and forest, where it nests in soil and concentrates its nest around or in the dead centers of stumps or wood in various stages of decomposition. It also nests in hollows in dead wood in tree trunks near the base of living trees, including eastern red cedar. This one was photographed at night in the midlands of South Carolina.
