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.

Dinomyrmex is a monotypic genus of ant containing the species Dinomyrmex gigas or giant forest ant. D. gigas is a large species of ant, native to Southeast Asian forests. It is one of the largest ants in existence, measuring in at 20.9 mm (0.82 in) for normal workers, and 28.1 mm (1.11 in) for the soldiers. Honeydew makes up 90% of their diet, but they will also consume insects and bird droppings. The ant is an effective forager, utilizing both efficient communication and recruitment. A handful of these ants may meet at night to engage in what has been observed to be ritual battle. These fights can continue for several months.

Colonies of this ant are found in a variety of habitats, where they excavate underground nests with galleries and chambers. In some parts of its range, the nests may be raided by slave-making ants, most notably Formica pergandei and Polyergus montivagus.

Labidus coecus is a species of army ant in the family Formicidae.

Lasioglossum leucopus is a Palearctic species of sweat bee.

Lasioglossum malachurum, the sharp-collared furrow bee, is a small European halictid bee. This species is obligately eusocial, with queens and workers, though the differences between the castes are not nearly as extreme as in honey bees. Early taxonomists mistakenly assigned the worker females to a different species from the queens. They are small, shiny, mostly black bees with off-white hair bands at the bases of the abdominal segments. L. malachurum is one of the more extensively studied species in the genus Lasioglossum, also known as sweat bees. Researchers have discovered that the eusocial behavior in colonies of L. malachurum varies significantly dependent upon the region of Europe in which each colony is located.

Lasioglossum nitidiusculum is a Palearctic species of sweat bee.

Lasioglossum villosulum is a Palearctic species of sweat bee.

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.

Megaponera analis is the sole species of the genus Megaponera. They are a strictly termite-eating (termitophagous) ponerine ant species widely distributed in Sub-Saharan Africa and most commonly known for their column-like raiding formation when attacking termite feeding sites. Their sophisticated raiding behaviour gave them the common name Matabele ant after the Matabele tribe, fierce warriors who overwhelmed various other tribes during the 1800s. With some individuals reaching up to 25 millimetres (0.98 in) in length, M. analis is one of the world's largest ants.

Myrmecina graminicola is a species of ant found throughout Northern Africa, Europe, Asia, and elsewhere in the Palearctic realm. Its colonies build nests in soil, under rocks, and in leaf litter. It was described in 1802 by Pierre André Latreille, initially in the genus Formica. They are not an aggressive species. When a worker encounters an intruder, it starts to play dead with its legs and antennae folded. They live in colonies that have less than 100 workers and one queen. Before mating, the female ant releases a pheromone that the male ant is attracted to this and the mating then occurs seconds after. The ant colonies move around following the queen’s pheromone trail.
