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.
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.
Andropogon gerardi, commonly known as big bluestem, is a species of tall grass native to much of the Great Plains and grassland regions of central and eastern North America. It is also known as tall bluestem, bluejoint, and turkeyfoot.
Crematogaster is an ecologically diverse genus of ants found worldwide, which are characterised by a distinctive heart-shaped gaster (abdomen), which gives them one of their common names, the Saint Valentine ant. Members of this genus are also known as cocktail ants because of their habit of raising their abdomens when alarmed. Most species are arboreal (tree-dwelling). These ants are sometimes known as acrobat ants.
The Alberta–British Columbia foothills forests are a temperate coniferous forests ecoregion of Western Canada, as defined by the World Wildlife Fund (WWF) categorization system. This ecoregion borders Canada's taiga and contains a mix of subarctic forest and temperate forest species as a result. This makes the region an ecotone region, or a region that acts as a buffer between two other biomes.
Tridens is a genus of perennial grasses in the family Poaceae native to the Americas.
Lasius fuliginosus, also known as the jet ant or jet black ant, is a species of ant in the subfamily Formicinae.
Daceton armigerum is a Neotropical species of arboreal ants, distributed throughout northern South America. D. armigerum combines several traits generally noted in some other arboreal ants i.e., populous colonies, large and/or polydomous nests, intra- and interspecific aggressiveness, trophobiosis, and capturing prey by spread-eagling them.
Crematogaster carinata is a species of ant in the tribe Crematogastrini. It was first described by Gustav Mayr in 1862. It is native to Central and South America, where it is a common species, forming large colonies in the canopy of the forest.
Myrmecophilus pergandei, the eastern ant cricket, is a species of ant cricket in the family Myrmecophilidae. It is found in North America. It is a wingless cricket that is an obligate kleptoparasite of ants living in their nests. They lack both wings and tympanal organs on the front tibia.
