An ant colony is a population of ants, typically from a single species, capable of maintaining their complete lifecycle. Ant colonies are eusocial, communal, and efficiently organized and are very much like those found in other social Hymenoptera, though the various groups of these developed sociality independently through convergent evolution. The typical colony consists of one or more egg-laying queens, numerous sterile females and, seasonally, many winged sexual males and females. In order to establish new colonies, ants undertake flights that occur at species-characteristic times of the day. Swarms of the winged sexuals depart the nest in search of other nests. The males die shortly thereafter, along with most of the females. A small percentage of the females survive to initiate new nests.
Carpenter ants are large ants indigenous to many forested parts of the world.
Tetramorium immigrans—also known as the immigrant pavement ant, pavement ant, and the sugar ant in parts of North America—is an ant native to Europe, which also occurs as an introduced pest in North America. Its common name comes from the fact that colonies in North America usually make their nests under pavement. This is one of the most commonly seen ants in North America, being well adapted to urban and suburban habitats. It is distinguished by a single pair of spines on the back, two nodes on the petiole, and grooves on the head and thorax.
The yellow meadow ant, also known as the yellow hill ant, is a species of ant occurring in Europe, Asia, and North Africa. Populations in North America are now considered a different, related species, Lasius brevicornis.
The banded sugar ant, also known as the sugar ant, is a species of ant native to Australia. A member of the genus Camponotus in the subfamily Formicinae, it was described by German entomologist Wilhelm Ferdinand Erichson in 1842. Its common name refers to the ant's liking for sugar and sweet food, as well as the distinctive orange-brown band that wraps around its gaster.
Iridomyrmex is a genus of ants called rainbow ants first described by Austrian entomologist Gustav Mayr in 1862. He placed the genus in the subfamily Dolichoderinae of the family Formicidae. It has 79 described species and five fossil species. Most of these ants are native to Australia; others are found in Asia and Oceania, and they have been introduced to Brazil, New Zealand, and the United Arab Emirates. Fossil species are known from China, France, and the United States.
The meat ant, also known as the gravel ant or southern meat ant, is a species of ant endemic to Australia. A member of the genus Iridomyrmex in the subfamily Dolichoderinae, it was described by British entomologist Frederick Smith in 1858. The meat ant is associated with many common names due to its appearance, nest-building behaviour and abundance, of which its specific name, purpureus, refers to its coloured appearance. It is among the best-known species of ant found throughout Australia; it occurs in almost all states and territories except for Tasmania. Its enormous distribution, aggression and ecological importance have made this ant a dominant species.
The black carpenter ant is one of the largest and most common species of carpenter ant native to the central and eastern United States as well as eastern Canada.
Camponotus vagus is a species of large, black, Palaearctic carpenter ant with a wide range that includes much of Europe, a large area of Asia, and part of Africa.
Colobopsis anderseni, synonym Camponotus anderseni, is a species of mangrove ant found in northern Australia.
Liometopum occidentale, also called the velvety tree ant, is a species of ant in the subfamily Dolichoderinae. Liometopum occidentale is often mistaken for carpenter ants by homeowners and pest management professionals. This mistaken identity is due to morphological and behavioral characteristics they share with carpenter ants; namely polymorphic workers, a smooth convex thoracic profile, and the tendency to excavate wood. Consequently, their importance as structural pests may be greatly under reported, especially in California, Oregon, and Washington, United States.
Liometopum apiculatum is a species of ant in the subfamily Dolichoderinae. Liometopum apiculatum ants are found in arid and semi-arid regions of southwestern United States and Mexico to Quintana Roo.
Formica incerta is a species of ant found in eastern North America. It is the most common species of Formica in many areas, and excavates underground nests with small entrance holes. Its diet includes nectar produced by extrafloral nectaries and honeydew, which it obtains from aphids and treehoppers. It is the main host for the slave-making ant Polyergus lucidus. F. incerta was first described by Italian entomologist Carlo Emery in 1893. Its specific name comes from the Latin incertus meaning "uncertain" and seems particularly apt given the subsequent uncertainty as to the validity of the species and the difficulty in distinguishing this ant from other species living in the same area.
Formica pallidefulva is a species of ant found in North America. It is a red to dark brown ant with a shiny body, and varies in shade across its range. Colonies of this ant are found in a variety of habitats, where they excavate underground nests with galleries and chambers. In some parts of its range, the nests may be raided by slave-making ants, most notably Formica pergandei and Polyergus montivagus.
Pogonomyrmex badius, or the Florida harvester ant, is a species of harvester ant in the genus Pogonomyrmex. It is the only Pogonomyrmex species found on the east coast of the United States and the only one in North America known to be polymorphic. The Florida Harvester ant is commonly found in Florida scrub and other similar habitats within the Atlantic coastal plain.
Camponotus herculeanus is a species of ant in the genus Camponotus, the carpenter ants, occurring in Northern Eurasia, from Norway to Eastern Siberia, and North America. First described as Formica herculeana by Linnaeus in 1758, the species was moved to Camponotus by Mayr in 1861.
Camponotus floridanus, or Florida carpenter ant, is a species of ant in the genus Camponotus. First described as Formica floridana by Buckley in 1866, the species was moved to Camponotus by Mayr in 1886. The ant is widespread in Florida and occurs as far north as North Carolina and as far west as Mississippi.
Novomessor ensifer is a species of ant endemic to Mexico. A member of the genus Novomessor in the subfamily Myrmicinae, it was first described by Swiss entomologist Auguste Forel in 1899. N. ensifer was originally a part of the genus Aphaenogaster until a recent phylogenetic study concluded that Novomessor was genetically distinct and should be separated. The ant is a medium-sized species, measuring 5.5 to 10 millimetres. The ant is ferruginous-colored in some certain parts of the body, and small workers (nanitics) in incipient colonies are noticeably different in color and body structure.
Camponotus castaneus, the red hazelnut carpenter ant, is a species of carpenter ant located in the eastern United States. It is a primarily orangish-red ant in the family Camponotus. Its workers are usually around 8-10 mm, and queens around 18-20 mm. As with most Camponotus species, camponotus castaneus has majors and super-majors, usually appearing in the second or third year of the colony's founding, majors are usually 10-14 mm, with super majors being around 13-17 mm. Camponotus castaneus has a generalist diet, feeding on insects and carbohydrates such as honeydew, which is easily accessible. The ant has a smooth thorax and abdomen, with 1 node separating them.
Camponotus ligniperda, the brown-black carpenter ant, is a common species of carpenter ant distributed widely throughout Europe. Found in a variety of woodland habitats, they commonly nest on the ground in dry tree stumps, dead fallen trees, or beneath stones and wooden logs that are partially buried. C. ligniperda is an ecologically dominant species wherever it is found due to both its large size and particularly aggressive nature.
