Dinoponera is a strictly South American genus of ant in the subfamily Ponerinae, commonly called tocandiras or giant Amazonian ants. [2] These ants are generally less well known than Paraponera clavata, the bullet ant, yet Dinoponera females may surpass 3–4 cm (1.2–1.6 in) in total body length, making them among the largest ants in the world.
They locate food through their sense of smell. [4] Nests can contain thousands of individuals, and such large nests may be noticed by the audible cracking sound the workers produce. The black carpenter ant cannot sting, but the larger workers can administer a sharp bite, which can become further irritated by the spraying of formic acid onto the ...

They are 5–7mm long and have delicate wings. Worker ...
Carpenter ants are generally large ants: workers are 4–7 mm long in small species and 7–13 mm in large species, queens are 9–20 mm long and males are 5–13 mm long. The bases of the antennae are separated from the clypeal border by a distance of at least the antennal scape's maximum diameter.
The little black ant (Monomorium minimum) is a species of ant native to North America. [1] It is a shiny black color, the workers about 1 to 2 mm long and the queens 4 to 5 mm long. It is a monomorphic species, with only one caste of worker, and polygyne, meaning a nest may have more than one queen. A colony is usually moderately sized with ...

Mating flights begin in the early morning when individuals of both sexes emerge from the colony. Males will leave for the mating sites first, followed by the females who likely follow male pheromones.
Pharaoh ant eyesight is poor and they possess on average 32 ommatidia. [6] The antennal segments end in a distinct club with three progressively longer segments. Males are about 3 millimetres (1 ⁄ 8 in) long, black, winged (but do not fly). Queens are dark red and 3.6–5.0 millimetres (1 ⁄ 8 – 3 ⁄ 16 in) long. They initially have wings ...
