Carpenter ant
Carpenter ants (''Camponotus'' spp.), also known as sugar ants, are large () ants indigenous to many forested parts of the world.
They build nests inside wood consisting of galleries chewed out with their mandibles, preferably in dead, damp wood. They do not consume the wood, however, unlike termites. Sometimes, carpenter ants hollow out sections of trees. They also commonly infest wooden buildings and structures, and are a widespread nuisance and major cause of structural damage. One of the most familiar species associated with human habitation in the United States is the black carpenter ant (''Camponotus pennsylvanicus''). The genus includes over 1,000 species.
==Habitat==
Carpenter ant species reside both outdoors and indoors in moist, decaying, or hollow wood, most commonly in forest environments. They cut "galleries" into the wood grain to provide passageways for movement from section to section of the nest. Certain parts of a house, such as around and under windows, roof eaves, decks and porches, are more likely to be infested by carpenter ants because these areas are most vulnerable to moisture.
Carpenter ants have been known to construct extensive underground tunneling systems. These systems often lead to and end at some food source – often aphid colonies, where the ants extract and feed on honeydew. These tunneling systems also often exist in trees. The colonies typically include a central "parent" colony surrounded and supplemented by smaller satellite colonies.〔Colony Size and Polygyny in Carpenter Ants (Hymenoptera: Formicidae) Roger D.
