Odontomachus hastatus is a species of ant from the complex Odontomachus hastatus, [1] [2] The species was originally described by Johan Christian Fabricius in 1804. [3]
Like other species of Odontomachus ants, the O. hastatus are easily recognised by their trap-like jaw, which with they catch and kill prey. [4]
The range of O. hastatus covers the rainforests of Central and South America. [5] This is confirmed in recent observations through crowdsourcing initiatives [3]
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.
Paraponera clavata, commonly known as the bullet ant, is a species of ant named for its extremely painful sting. It inhabits humid lowland rainforests in Central and South America.
An instar is a developmental stage of arthropods, such as insects, between each moult (ecdysis), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars.
Ponerinae, the ponerine ants, is a subfamily of ants in the Poneromorph subfamilies group, with about 1,600 species in 47 extant genera, including Dinoponera gigantea - one of the world's largest species of ant. Mated workers have replaced the queen as the functional egg-layers in several species of ponerine ants. In such queenless species, the reproductive status of workers can only be determined through ovarian dissections.
Myrmecia is a genus of ants first established by Danish zoologist Johan Christian Fabricius in 1804. The genus is a member of the subfamily Myrmeciinae of the family Formicidae. Myrmecia is a large genus of ants, comprising at least 93 species that are found throughout Australia and its coastal islands, while a single species is only known from New Caledonia. One species has been introduced out of its natural distribution and was found in New Zealand in 1940, but the ant was last seen in 1981. These ants are commonly known as bull ants, bulldog ants or jack jumper ants, and are also associated with many other common names. They are characterized by their extreme aggressiveness, ferocity, and painful stings. Some species are known for the jumping behavior they exhibit when agitated.
Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant, the erratic ant, the odorous house ant, and the cone ant. The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic realms, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions.
Odontomachus is a genus of ants commonly called trap-jaw ants found in the tropics and subtropics throughout the world.
Odontomachus bauri is a species of ponerinae ant known as trap jaw ants. The trap jaw consists of mandibles which contain a spring-loaded catch mechanism.
Pachycondyla is a ponerine genus of ants found in the Neotropics.
Odontomachus brunneus is a species of ant in the subfamily Ponerinae, found in the southeastern United States, parts of Central America, and the West Indies.
Atta cephalotes is a species of leafcutter ant in the tribe Attini. A single colony of ants can contain up to 5 million members, and each colony has one queen that can live more than 15 years. The colony comprises different castes, known as "task partitioning", and each caste has a different job to do.
A gamergate is a mated worker ant that can reproduce sexually, i.e., lay fertilized eggs that will develop as females. In the vast majority of ant species, workers are sterile and gamergates are restricted to taxa where the workers have a functional sperm reservoir ('spermatheca'). In some species, gamergates reproduce in addition to winged queens, while in other species the queen caste has been completely replaced by gamergates. In gamergate species, all workers in a colony have similar reproductive potentials, but as a result of physical interactions, a dominance hierarchy is formed and only one or a few top-ranking workers can mate and produce eggs. Subsequently however, aggression is no longer needed as gamergates secrete chemical signals that inform the other workers of their reproductive status in the colony.
Odontomachus paleomyagra is an extinct species of formicid in the ant subfamily Ponerinae known from a Miocene fossil found in Europe.
Odontomachus assiniensis is a species of ponerinae ant known as a trap-jaw ant. The trap-jaw mechanism consists of mandibles which spring shut when triggered. This ant was first described in 1892 by the Italian entomologist Carlo Emery. The type locality is the Ivory Coast, where the coastal site of Assini, in the southeast, gIves the specific name assiniensis, "of Assini".
Odontomachus spinifer is an extinct species of ant in the subfamily Ponerinae known from one possibly Miocene fossil found on Hispaniola. O. spinifer is one of two species in the ant genus Odontomachus to have been described from fossils found in Dominican amber and is one of a number of Odontomachus species found in the Greater Antilles.
Odontomachus pseudobauri is an extinct species of ant in the subfamily Ponerinae known from one possibly Miocene fossil found on Hispaniola. O. pseudobauri is one of two species in the ant genus Odontomachus to have been described from fossils found in Dominican amber and is one of a number of Odontomachus species found in the Greater Antilles.
Formica archboldi is a species of ant in the family Formicidae. They are known for their abnormal behavior, which includes the collection and storage of Odontomachus (trap-jaw) ant skulls.
Ondontomachini is a tribe of ants which belongs to the subfamily Ponerinae. Ondontomachini includes two genera: Odontomachus and Anochetus.
