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]
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 ...
Members of this group have enormous gasters and can regurgitate their stored food when needed. In this way, the colony has a cushion against food shortages. [21] Pharaoh ants have a sophisticated strategy for food preference. They implement two related behaviors. The first is known as satiation.
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.
Carebara species have permanent nests, while real army ants have only temporary nests (Dorylus) or form a bivouac with their own bodies (Eciton). Colonies of real army ants have only one queen, so when she dies, the workers may try to join another colony, or the rest of the colony also dies; Carebara colonies can have many (up to 16) queens.
The tawny crazy ant [2] [3] [4] or Rasberry crazy ant, [2] Nylanderia fulva, is an ant originating in South America. Like the longhorn crazy ant (Paratrechina longicornis), this species is called "crazy ant" because of its quick, unpredictable movements (the related N. pubens is known as the "Caribbean crazy ant").
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Experiment have sought to identify how ants identify corpses that need to be disposed and have found that in some cases it is the presence of oleic and linoleic acid, produced by the breakdown of fats. This breakdown can take about two days. There are also differences in how dead nestmates and non-nestmates are treated.
