Carpenter Ant

Florida carpenter ant, Camponotus abdominalis floridanus. It is a large ant, 5 mm to 10 mm long, with a yellowish-red thorax and black abdomen. It nests in mulch, logs and in wall voids of houses. It can hollow out wood in order to make its nest, depositing wood pieces nearby. The ant has one node on the petiole. Workers are polymorphic (many sizes), and colonies are monogyne (one queen).
