3.5–4.5 mm long, slim, colour black. Only produced by queens when the nuptial flights are approaching. They appear with a dark glossy body with a different shape from the workers, almost resembling a wasp in appearance. They have wing muscles which stand out from the rest of the body. They are 5–7mm long and have delicate wings. Worker ...
"Scout" ants are the first ones out of the mound every morning. They seek food, and mark their path as they return to the mound to alert the worker ants. The worker ants follow the scent trail and collect the food. Other worker ants clean, extend, and generally tend to the mound, the queen, and the brood. All the ants in the colonies are ...
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.
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.
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 that are lost soon after mating, but do not fly. [7]
Megaponera is a genus of ponerine ant first defined by Gustav Mayr in 1862 for the species Formica analis Latreille, 1802, [8] the sole species belonging to the genus to date. . In 1994 William L. Brown Jr. synonymised the genus under Pachycondyla even though he lacked phylogenetic justification, thereby changing the name from Megaponera foetens to Pachycondyla analis.
A venomous spider bite (like this brown recluse bite) can cause a red or purplish rash radiating from the site of the bite. There are only a few species of spiders in the U.S. that can bite humans.
The ants do not pose any threat to humans, because they are incapable of stinging and can only spray formic acid. However, the larger soldiers can inflict a painful bite with their powerful jaws, and the formic acid they spray is corrosive to human skin. [28] [32] [63] [64] The eggs of the species were consumed by the Indigenous Australians. [65]
