Lasius emarginatus is a species of boreal formicine ants.
Lasius emarginatus is a small ant, reaching a length of 3–5.5 mm in the workers, 7–10 mm in the females and 7–14.5 mm in males. In workers and females the thorax is reddish or brownish-red, while the head and the abdomen are brown. Males are completely brown. [1]
The longevity of the queen reaches up to 30 years, but for workers it is limited to 3 years. The species is omnivore. Colonies are monogynous (one queen per colony). They are not aggressive but they do not mind attacking a potential predator or another colony to expand their hunting and harvesting territory.[ citation needed ]
This species is present in the Western Palearctic (Europe, the Caucasus, and Asia Minor).[ citation needed ] As an invasive species, it is now found in Manhattan where it has taken on the niche of above-ground-level floors in taller buildings. [2]
The nuptial flight happens between June and August. Although normal independent colony foundation is usual, it can also be achieved through Pleometrosis, a process in which several queens work together to get the colony started, but eventually the future workers will kill or drive away all queens but the dominant one.
Formica exsecta is a species of ant found from Western Europe to Asia.
The black garden ant, also known as the common black ant, is a formicine ant, the type species of the subgenus Lasius, which is found across Europe and in some parts of North America, South America, Asia and Australasia. The European species was split into two species; L. niger, which are found in open areas; and L. platythorax, which is found in forest habitats. It is monogynous, meaning colonies contain a single queen.
An ant colony is a population of a single ant species capable to maintain its 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.
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 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.
Atta sexdens is a species of leafcutter ant belonging to the tribe Attini, native to the New World, from the southern United States (Texas) to northern Argentina. They are absent from Chile. They cut leaves to provide a substrate for the fungus farms which are their principal source of food. Their societies are among the most complex found in social insects. A. sexdens is an ecologically important species, but also an agricultural pest. Other Atta species, such as Atta texana, Atta cephalotes and others, have similar behavior and ecology.
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.
A queen ant is an adult, reproducing female ant in an ant colony; generally she will be the mother of all the other ants in that colony. Some female ants, such as the Cataglyphis, do not need to mate to produce offspring, reproducing through asexual parthenogenesis or cloning, and all of those offspring will be female. Others, like those in the genus Crematogaster, mate in a nuptial flight. Queen offspring ants develop from larvae specially fed in order to become sexually mature among most species. Depending on the species, there can be either a single mother queen, or potentially hundreds of fertile queens in some species. A queen of Lasius niger was held in captivity by German entomologist Hermann Appel for 283⁄4 years; also a Pogonomyrmex owyheei has maximum estimated longevity of 30 years in the field.
Lasius umbratus, colloquially known as the yellow shadow ant and yellow lawn ant, is a palearctic species of parasitic ant distributed across Eurasia and the Maghreb region of Africa. It was once thought that this species occurred in North America as well, but comparative genomic studies indicate the Afro-Eurasian and American populations are discrete and not closely related enough to represent a single species. The North American populations are now treated as a different species, Lasius aphidicola.
Carebara diversa, is a species of marauder ant widely distributed throughout Asia.
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.
Dorylus laevigatus is a member of the army ant genus Dorylus, or Old World army ants. More specifically known as "driver ants", the genus Dorylus is abundant throughout Africa and stretches into tropical Asia, where D. laevigatus is primarily found. They are a eusocial colony-forming species, which live primarily underground, rarely venturing to the surface for any reason. D. laevigatus colonies are small for army ants, estimated averages falling between 30,000 and 1,000,000 individuals.
Lasius fuliginosus, also known as the jet ant or jet black ant, is a species of ant in the subfamily Formicinae.
Crematogaster scutellaris is a species of ant belonging to the family Formicidae, subfamily Myrmicinae.
Leptothorax acervorum is a small brown to yellow ant in the subfamily Myrmicinae. It was first described by Johan Christian Fabricius in 1793. L. acervorum is vastly distributed across the globe, most commonly found in the coniferous forests of Central, Western and Northern Europe. The morphology of L. acervorum is extremely similar to that of other Leptothorax ants. The difference arises in the two-toned appearance of L. acervorum, with the head and metasoma being darker than the mesosoma segment of the body, and hair across its body. Following Bergmann's rule—unusually, for ectothermic animals—body size increases with latitude.
Formica truncorum is a species of wood ant from the genus Formica. It is distributed across a variety of locations worldwide, including central Europe and Japan. Workers can range from 3.5 to 9.0mm and are uniquely characterized by small hairs covering their entire bodies. Like all other ants, F. truncorum is eusocial and demonstrates many cooperative behaviors that are unique to its order. Colonies are either monogynous, with one queen, or polygynous, with many queens, and these two types of colonies differ in many characteristics.
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.
Lasius brunneus is a species of ant in the genus Lasius. The species is widely distributed in Europe, from Sweden in the north to Anatolia in the south. In England this species is almost always found nesting in oak trees or rotting wood mainly foraging in trees but has also been found under stones and foraging on the ground. It is thought to be underrecorded but is fairly common especially in the South East.
