Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists.
Honeypot ants, also called honey ants, are ants which have specialized workers that consume large amounts of food to the point that their abdomens swell enormously. Other ants then extract nourishment from them, through the process of trophallaxis. They function as living larders. Honeypot ants belong to any of several genera, including Myrmecocystus and Camponotus. They were first documented in 1881 by Henry C. McCook, and described further in 1908 by William Morton Wheeler.
Pogonomyrmex barbatus is a species of harvester ant from the genus Pogonomyrmex. Its common names include red ant and red harvester ant. These large ants prefer arid chaparral habitats and are native to the Southwestern United States. Nests are made underground in exposed areas. Their diets consist primarily of seeds, and they consequently participate in myrmecochory, an ant-plant interaction through which the ants gain nutrients and the plants benefit through seed dispersal. Red harvester ants are often mistaken for fire ants, but are not closely related to any fire ant species, native or introduced.
Carpenter ants are large ants indigenous to many forested parts of the world.
The pharaoh ant is a small (2 mm) yellow or light brown, almost transparent ant notorious for being a major indoor nuisance pest, especially in hospitals. A cryptogenic species, it has now been introduced to virtually every area of the world, including Europe, the Americas, Australasia and Southeast Asia. It is a major pest in the United States, Australia, and Europe. The ant's common name is possibly derived from the mistaken belief that it was one of the Egyptian (pharaonic) plagues.
Tapinoma sessile is a species of small ant that goes by the common names odorous house ant, sugar ant, stink ant, and coconut ant. Their colonies are polydomous and polygynous. Like many social insects, T. sessile employs complex foraging strategies, allocates food depending on environmental conditions, and engages in competition with other insects.
The black-chinned sparrow is a small bird in the genus Spizella, in the New World sparrow family Passerellidae. It is found in the southwestern United States and throughout much of Mexico north of the Isthmus of Tehuantepec; most populations in the US migrate south after breeding while those in Mexico are resident. It is a slim, long-tailed bird, primarily gray with a reddish-brown back streaked with black, brown wings and tail, a pink beak, and brownish legs and feet. In the breeding season, the male shows black on his throat, chin, and the front of his face. Females, youngsters and nonbreeding males show little or no black in these areas. An unobtrusive bird, it spends much of its time foraging slowly along the ground, either alone or in small groups, sometimes mixing with other Spizella species. It is an omnivore, feeding primarily on seeds during the winter and insects during the summer. It builds a cup-shaped nest of grasses, rootlets, or plant fibers, into which the female lays 2–5 pale blue eggs. The female does most or all of the egg incubation, but both parents feed the hatched nestlings.
Dorymyrmex is a genus of ants in the subfamily Dolichoderinae.
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.
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.
Dorymyrmex insanus is a species of pyramid ant, one of several species known as crazy ants, for their "frenetic" movement and swarming behavior. It is found in hot, dry habitats in the southern parts of the United States, much of Central America, and tropical South America. Dorymyrmex insanus is listed as Vulnerable by the International Union for Conservation of Nature (IUCN).
Tool use by non-humans is a phenomenon in which a non-human animal uses any kind of tool in order to achieve a goal such as acquiring food and water, grooming, combat, defence, communication, recreation or construction. Originally thought to be a skill possessed only by humans, some tool use requires a sophisticated level of cognition. There is considerable discussion about the definition of what constitutes a tool and therefore which behaviours can be considered true examples of tool use. A wide range of animals, including mammals, birds, fish, cephalopods, and insects, are considered to use tools.
Pogonomyrmex occidentalis, or the western harvester ant, is a species of ant that inhabits the deserts and arid grasslands of the American West at or below 6,300 feet (1,900 m). Like other harvester ants in the genus Pogonomyrmex, it is so called because of its habit of collecting edible seeds and other food items. The specific epithet "occidentalis", meaning "of the west", refers to the fact that it is characteristic of the interior of the Western United States; its mounds of gravel, surrounded by areas denuded of plant life, are a conspicuous feature of rangeland. When numerous, they may cause such loss of grazing plants and seeds, as to constitute both a severe ecological and economic burden. They have a painful and venomous sting.
Myrmecocystus mexicanus is a species of ant in the genus Myrmecocystus, which is one of the six genera that bear the common name "honey ant" or "honeypot ant", due to curious behavior where some of the workers will swell with liquid food until they become immobile and hang from the ceilings of nest chambers, acting as living food storage for the colony. Honey ants are found in North America, Australia, and Africa. Ant species belonging to the genus Myrmecocystus reside in North America. M. mexicanus in particular is found in the southwestern United States and parts of Mexico.
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.
Novomessor cockerelli is a species of ant in the subfamily Myrmicinae. It is native to the deserts of the Southwestern United States and Mexico. It lives in large underground colonies in which there is a single queen. The worker ants leave the nest daily to forage for seeds, plant material and dead insects.
Dorymyrmex bureni, also known as Buren's pyramid ant, is a species of ant in the genus Dorymyrmex. Described by Trager in 1988, the species is endemic to the United States. Pyramid ants are medium-sized ants, ranging from 2–4 mm. They are light orange in color and fast moving. Unlike other ant species in the area like the red imported fire ant, this species is relatively harmless to humans and unable to sting. The workers have a foul smelling coconut odor when crushed. Dorymyrmex bureni hunt living insects, even other winged ants. They also search for sap-sucking insects from which they collect honeydew. On the head of these ants are curved hairs, used for transporting beads of damp sand. Colonies are small. Nests usually have a single entrance with a mound of sand shaped like a crater. Dorymyrmex bureni prefer sandy soil. This species of ant is not an indoor pest, and the use of pesticides to control them is not necessary. They are found throughout the southeastern United States.
Melipona bicolorLepeletier, 1836, commonly known as Guaraipo or Guarupu, is a eusocial bee found primarily in South America. It is an inhabitant of the Araucaria Forest and the Atlantic Rainforest, and is most commonly found from South to East Brazil, Bolivia, Argentina, and Paraguay. It prefers to nest close to the soil, in hollowed trunks or roots of trees. M. bicolor is a member of the tribe Meliponini, and is therefore a stingless bee. This species is unique among the stingless bees species because it is polygynous, which is rare for eusocial bees.
Novomessor albisetosus, also known as the desert harvester ant, is a species of ant found in the United States and Mexico. A member of the genus Novomessor in the subfamily Myrmicinae, it was first described by Austrian entomologist Gustav Mayr in 1886. It was originally placed in the genus Aphaenogaster, but a recent phylogenetic study concluded that it is genetically distinct and should be separated. It is a medium-sized species, measuring 6 to 8.5 millimeters and has a ferruginous body color. It can be distinguished from other Novomessor species by its shorter head and subparallel eyes.
Messor capitatus is an ant species part of the genus Messor. This genus includes about 40 specialized species that are found in dry areas of Mediterranean countries such as Africa, Southern Europe, and Asia. Messor capitatus are known as an Old World species because they release trail pheromones from the Dufour gland instead of from poison glands. Messor capitatus are known as individual foragers that collect food independently of one another but sometimes will also use group foraging to form irregular, broad columns. Messor capitatus main food source is seeds but they also will eat remains of plants and animals.
