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 ...
Third, not all eucharitids have a significant effect on the size of their hosts' colony. [8] Orasema species are sometimes used as means of biological control for many ants, including the fire ant and little fire ant, because pesticides can cause damage to the environment, and they do not always work on fire ants. In addition, at least two ...
Camponotus ants do not have a metapleural gland [106] and Camponotus maculatus as well as C. floridanus workers have been found to amputate the affected legs of nestmates when the femur is injured. A femur injury carries a greater risk of infection unlike a tibia injury.
During diapause, developing ants are usually kept at this stage. Pupae. Once the larvae have grown large enough, they pupate. Unlike many other ant species, the pupae of C. castaneus are not "naked" and, instead, are encased in oval cocoons which are spun around them, usually by the queen and worker ants.
The secretion is often used in communication to mark members of the colony, to mark hosts (parasitic wasps), during slave raids (ants), for territory marking (ants), to signal fertility, to attract a member of the opposite sex, to give an alarm warning (ants) or to mark a trail (ants).
Ant undertakers have a slightly altered development cycle, and are much more likely than other ants to handle corpse removal. They are not restricted to performing only this task, but they do exhibit different behavioral and movement patterns than other members of the colony, which assist them in this task. [ 6 ]
Scientists found that 10 or more fire ants can stick together to build a life-saving raft in floods.. Fewer than 10 ants can’t form a stable raft because the “Cheerios effect” of fluid ...
Honey ants are unique in using their own bodies as living storage, used later by their fellow ants when food is otherwise scarce. When the liquid stored inside a honeypot ant is needed, the worker ants stroke the antennae of the honeypot ant, causing the honeypot ant to regurgitate the stored liquid from its crop. [4] [5]
