Lasius speculiventris is a species of ant that is commonly found in the northern United States and lives in forests, woodlands, and meadows. [2]
Lasius is a genus of formicine ants. The type species for this genus is the black garden ant, Lasius niger. Other major members, which live in drier heathland, are the cornfield ant, L. neoniger, and L. alienus. Other species include the temporary social parasites of the L. mixtus group and the hyper-social parasite Lasius fuliginosus. Lasius flavus is also a commonly seen species, building grassy hillocks in undisturbed pasture. In the Alps, these mounds - always aligned east to catch the first rays of the rising sun - have been traditionally used by goatherds as natural compasses. Species in the subgenus Acanthomyops, in particular L. interjectus and L. claviger, are commonly known as citronella ants due to their citronella-like smell.
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.
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 murphyi is a species of ant in the genus Lasius. It is endemic to the United States and Canada.
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.
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.
Lasius alienus, or cornfield ant, is a species of ant in the subfamily Formicinae. Workers have a length of about 2–4 mm, Queens are larger (7–9 mm).
Lasius fuliginosus, also known as the jet ant or jet black ant, is a species of ant in the subfamily Formicinae.
Lasius emarginatus is a species of boreal formicine ants.
Lasius claviger, or the smaller yellow ant, is a species of ant belonging to the genus Lasius, formerly a part of the genus Acanthomyops. Described in 1862 by Roger, the species is native to the United States.
Lasius interjectus, commonly known as the larger yellow ant, is a species of ant belonging to the genus Lasius, and was formerly a part of the genus Acanthomyops. Described in 1866 by Mayr, the species is native to the United States.
Lasius mexicanus is a species of ant belonging to the genus Lasius, formerly a part of the genus Acanthomyops. Described in 1914 by William Morton Wheeler, the species is native to Mexico.
Lasius neoniger, also known as the turfgrass ant, Labour day ant, cornfield ant or nuisance ant, is a species of ant in the genus Lasius. Found in North America, the species is common in the eastern United States and Canada, though they can be found all over the continent. They are usually light brown in color, with a slightly darker head.
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.
Lasius subumbratus is a species of ant in the family Formicidae.
Lasius grandis is a species of ant from the genus Lasius. The species was originally described by Forel in 1909. It occurs in the Mediterranean region of Europe and North Africa, more precisely in the Portuguese and Spanish mainland, in Andorra, the Azores, the Balearic Islands and Canary Islands.
Batrisus formicarius is a European species of ant-loving beetle placed within the Pselaphinae subfamily of the Staphylinidae family.
