C. carinata, specimen CASENT0919696, profile view

Crematogaster carinata is a species of ant in the tribe Crematogastrini.^[2] It was first described by Gustav Mayr in 1862.^[2] It is native to Central and South America, where it is a common species, forming large colonies in the canopy of the forest.

Description

Workers of C. carinata are small, and there is only one class. The head, thorax and abdomen are reddish brown, while the mandibles, the tips of the antennae and the tarsi are yellowish.^[3]

Distribution and habitat

Crematogaster carinata is native to the Neotropics, its range extending from Costa Rica southward to Bolivia and southern Brazil. It is a widespread species and is found in humid rainforest, and other types of wet lowland forest, at altitudes of up to 2,000 m (6,600 ft).^[3]

In a survey of ants in a 0.16 km² (190,000 sq yd) of lowland primary rainforest in Ecuador, 489 species of ant were found. C. carinata were the most common species found in the canopy, the electric ant (Wasmannia auropunctata) was the most abundant on the ground while the army ant ( Labidus coecus ) was the most abundant below ground.^[4]

Ecology

Crematogaster carinata is an omnivore, foraging by day and by night for any foodstuff which is available, and making use of any extrafloral nectaries the host tree may provide. The ants are also scavengers, carrying dead and injured insects back to the nest, and feeding on the honeydew produced by scale insects. The ants actively build nests out of a material known as carton, collecting plant fibres or other materials for the purpose, and they also create carton structures to shelter the scale insects from which they get honeydew. Carton material is also used to enclose the roots of epiphytes, but this species is less active in carton construction than are some other species.^[3]^[5] The enclosed mass of debris and soil from which the epiphytes grow can be anything from the size of a nut to the size of an orange, or larger. It is known as an ant garden and the ants carry seeds of suitable epiphytic species to "plant" in their garden.^[6]

In many parts of its range, C. carinata is polygynous, and a single large colony may form in the tree canopy covering a number of large trees. There is not one central nest, instead there are a number of locations where clusters of small nests, each with one or more queens, multiple workers and brood (eggs, larvae and pupae), are to be found. This species forms parabiotic associations with several other species of ant, using the same foraging trails and with the two species sharing nests. Although the two species occupy the same nest, any chamber that contains brood is used exclusively by the ants whose brood it is.^[3] In a parabiotic association with Dolichoderus debilis , several nests in a pile of dead branches were adjoining and intermingled with each other, but on the whole, the Crematogaster chambers were small and were near the periphery while the Dolichoderus chambers were larger and more central. Some chambers contained both species, but these housed no brood.^[3] When Crematogaster carinata shares a nest with the much fiercer Camponotus femoratus , it may benefit from that ant's aggression.^[4] In circumstances where it associates with a larger species of ant, it forms larger and more fully developed ant gardens.^[3] In some parts of its range, such as western Costa Rica, it is monogynous, with a single queen in the colony.^[3]

Paraponera clavata is a species of ant, commonly known as the bullet ant, named for its extremely painful sting. It inhabits humid lowland rainforests in Central and South America.

Formica rufa, also known as the red wood ant, southern wood ant, or horse ant, is a boreal member of the Formica rufa group of ants, and is the type species for that group. It is native to Europe and Anatolia, but is also found in North America, in both coniferous and broad-leaf broken woodland and parkland. Workers are colored red and brownish-black, with a dorsal dark patch on the head and promensonotum, and are polymorphic, measuring 4.5–9 mm in length. They have large mandibles, and like many other ant species, they are able to spray formic acid from their abdomens as a defence. Formic acid was first extracted in 1671 by the English naturalist John Ray by distilling a large number of crushed ants of this species. These ants primarily eat honeydew from aphids. Some groups form large networks of connected nests with multiple queen colonies, while others have single-queen colonies.

Myrmecophily is the term applied to positive interspecies associations between ants and a variety of other organisms, such as plants, other arthropods, and fungi. Myrmecophily refers to mutualistic associations with ants, though in its more general use, the term may also refer to commensal or even parasitic interactions.

Lasius neglectus is a polygynous, sometimes invasive, ant of the genus Lasius. The ant was identified in 1990 after establishing a colony in Budapest, Hungary. Superficially, they are similar in appearance to the common black garden ant, Lasius niger, but have significantly different behavioural patterns, particularly in the social structure within colonies.

Crematogaster ashmeadi, commonly known as the acrobat ant, is an arboreal ant widespread in the Southeastern United States. It nests and forages almost exclusively above ground level, often found in treetops and on lianas. It is one of eleven species in the genus Crematogaster that is native to eastern North America. This ant species has been observed to raid wasp nests, including the species Mischocyttarus mexicanus, and to forage on their brood. It is the most dominant arboreal ant in the pine forests of the coastal plains of northern Florida. Colonies of these ants inhabit a majority of pine trees in the area, living in chambers in the outer bark of living trees that have been abandoned by bark-mining caterpillars, usually of the family Cossidae. C. ashmeadi does little to no excavation of its own, relying solely on chambers bored out by other insects.

Cephalotes atratus is a species of arboreal ant in the genus Cephalotes, a genus characterized by its odd shaped head. These ants are known as gliding ants because of their ability to "parachute" by steering their fall if they lose their footing.

Pheidole megacephala is a species of ant in the family Formicidae. It is commonly known as the big-headed ant in the USA and the coastal brown ant in Australia. It is a very successful invasive species and is considered a danger to native ants in Australia and other places. It has been nominated as one of the hundred "World's worst" invaders.

The longhorn crazy ant, also known as "black crazy ant", is a species of small, dark-coloured insect in the family Formicidae. These ants are commonly called "crazy ants" because instead of following straight lines, they dash around erratically. They have a broad distribution, including much of the tropics and subtropics, and are also found in buildings in more temperate regions, making them one of the most widespread ant species in the world. This species, as well as all others in the ant subfamily Formicinae, cannot sting.

Bombus transversalis is a bumblebee specifically native to the Amazon Basin. It is most notable for its surface level colonies which are built by the workers on the rainforest floor. Unlike its relatives, B. transversalis is able to thrive in a humid climate and fend off a wide range of predators because of its resilient nests. While there is great deal of information pertaining to their nests and foraging abilities, there is much more to be learned about relationships within the colony and life cycle of the bee.

An ant garden is a mutualistic interaction between certain species of arboreal ants and various epiphytic plants. It is a structure made in the tree canopy by the ants that is filled with debris and other organic matter in which epiphytes grow. The ants benefit from this arrangement by having a stable framework on which to build their nest while the plants benefit by obtaining nutrients from the soil and from the moisture retained there.
