Driver ants. Driver ants, from the genus Dorylus, are found in the Old World, especially West Africa and the Congo Basin. Unlike the army ants of the New World, Old World army ants have a functional sting but rarely use it, preferring their razor-sharp, falcate mandibles for defense instead. Dorylus spp. colonies also reach larger sizes than ...
They have a jugal anal lobe (a portion of the hindwing), a feature found in many primitive ants, and basal hamuli (hook-like projections that link the forewings and hindwings). Most male specimens collected have two tibial spurs (spines located on the distal end of the tibia); the first spur is a long calcar and the second spur is short and thick.
However, some ants, such as Australia's bulldog ant, have excellent vision and are capable of discriminating the distance and size of objects moving nearly a meter away. [45] Based on experiments conducted to test their ability to differentiate between selected wavelengths of light, some ant species such as Camponotus blandus, Solenopsis ...
This allows the pharaoh ants to be able to exert social control over the size of the colony and the size of each caste. In the average nest, there are around 170 ± 8 queens, which comprises around 5.2% of the total population, whereas there are around 2185 ± 49 workers, which make up around 66.6% of the population.
The jack jumper ant (Myrmecia pilosula), also known as the jack jumper, jumping jack, hopper ant, or jumper ant, is a species of venomous ant native to Australia.Most frequently found in Tasmania and southeast mainland Australia, it is a member of the genus Myrmecia, subfamily Myrmeciinae, and was formally described and named by British entomologist Frederick Smith in 1858.
Plerergates can live anywhere in the nest, but in the wild, they are found deep underground, unable to move, swollen to the size of grapes. [7] In Camponotus inflatus in Australia, repletes formed 49% (516 ants) of a colony of 1063 ants, and 46% (1835 ants) of a colony of 4019 ants. The smaller colony contained six wingless queens.
The number of thief ants in a colony depends on the location. Colonies with a reliable and ready food source do not have as many workers because food is readily available. Since ants of this species are so small, they can colonize just about anywhere. They can live in people's homes without them ever knowing that they have an infestation of ...
The pavement ant is dark brown to blackish, and 2.5–4 millimeters (0.10–0.16 in) long. A colony is composed of workers, alates, and a queen. Workers do have a small stinger, which can cause mild discomfort in humans but is essentially harmless. Alates, or new queen ants and drones, have wings, and are at least twice as large as the workers ...
