The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development.
The name army ant (or legionary ant or marabunta) is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited area.
Plagiolepidini are an ant tribe from the subfamily Formicinae.
Paratrechina is one of seven ant genera in the Prenolepis genus-group from the subfamily Formicinae. Six species are included in Paratrechina; one of which, the longhorn crazy ant, is a widespread, pantropical pest.
Myrmekiaphila is a genus of North American mygalomorph trapdoor spiders in the family Euctenizidae, and was first described by G. F. Atkinson in 1886. All described species are endemic to the southeastern United States.
The tawny crazy ant or Rasberry crazy ant, Nylanderia fulva, is an ant originating in South America. Like the longhorn crazy ant, this species is called "crazy ant" because of its quick, unpredictable movements. It is sometimes called the "Rasberry crazy ant" in Texas after the exterminator Tom Rasberry, who noticed that the ants were increasing in numbers in 2002. Scientists have reorganised the genera taxonomy within this clade of ants, and now it is identified as Nylanderia fulva.
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.
Ficus subpisocarpa is a species of small deciduous tree native to Japan, China, Taiwan and southeast Asia to the Moluccas (Ceram). Two subspecies are recognised. Terrestrial or hemiepiphytic, it reaches a height of 7 m (23 ft). Ants predominantly of the genus Crematogaster have been recorded living in stem cavities. Ficus subpisocarpa is pollinated by Platyscapa ishiiana (Agaonidae).
Euprenolepis is a Southeast Asian genus of ants in the subfamily Formicinae with eight recognized species.
Nylanderia is a large genus of ants in the subfamily Formicinae. The genus has a nearly cosmopolitan distribution with species inhabiting a wide array of habitats in almost all geographic regions. Nylanderia, currently containing over 110 species, is an ecologically important genus, with some species reported as being invasive. The ants are small to medium in size and range in color from pale yellow to black.
Paraparatrechina is a genus of small ants in the subfamily Formicinae. The genus contains 31 species distributed in the tropics of Africa, Asia and Australia.
Prenolepis is a genus of ants in the subfamily Formicinae. Most species are found in southeastern Asia and southern China, but the genus has a wide distribution with species known from North America, southern Europe, Anatolia, Cuba, Haiti, and West Africa.
Paratrechina zanjensis is an African species of ant in the genus Paratrechina. It is one of two species in the genus, the other being the longhorn crazy ant.
Aenictus gutianshanensis is a Chinese species of army ant in the genus Aenictus. The species is known only from a single colony. Little is known about its biology, but it is probably most closely related to A. vieti.
Prenolepis imparis, commonly known as the winter ant, false honey ant, or false honeypot ant, is a species of ant in the genus Prenolepis. The species is found in North America, from Canada to Mexico, nesting deep within the ground. Unusual among ants, Prenolepis imparis prefers lower temperatures, including near freezing, and is only active outside the nest during winter and early spring. Prenolepis imparis enters a hibernation-like state called aestivation during the summer.
Macrodinychus multispinosus is a mite that lives as an ectoparasitoid on the invasive Paratrechina longicornis. These mites complete their development on a single host, sucking all of its body content and therefore killing it. This is the ninth species of Macrodinychus reported as ant parasite, and the third known as parasitoid of invasive ants, confirming a unique habit in the evolution of mite feeding strategies and suggesting that the entire genus might be parasitic on ants.
Nylanderia pygmaea is an extinct species of formicid in the ant subfamily Formicinae known from fossils found in the Baltic region.
In ecology, a tramp species is an organism that has been spread globally by human activities. The term was coined by William Morton Wheeler in the bulletin of the American museum of natural history in 1906, used to describe ants that “have made their way as well known tramps or stow-aways[sic] to many islands The term has since widened to include non-ant organisms, but remains most popular in myrmecology. Tramp species have been noted in multiple phyla spanning both animal and plant kingdoms, including but not limited to arthropods, mollusca, bryophytes, and pteridophytes. The term "tramp species" was popularized and given a more set definition by Luc Passera in his chapter of David F William's 1994 book Exotic Ants: Biology, Impact, And Control Of Introduced Species.
