Colonies of army ants are large compared to the colonies of other Formicidae. Colonies can have over 15 million workers and can transport 3000 prey (items) per hour during the raid period. [14] [20] When army ants forage, the trails that are formed can be over 20 m (66 ft) wide and over 100 m (330 ft) long. [20]
The reasons that can lead ant colonies to clash are varied and depend on the species, locations, and contexts. For a number of them, such as leafcutter ants Atta laevigata, wood ants of the genus Formica, certain species of the genus Carebara, or giant ants Dinomyrmex gigas, it is a matter of territory covered and thus the available food for the different colonies.
There are ant-mimicking staphylinid beetles, shaped like the ants they follow, that run with the swarm, some of them preying on stragglers or other insects injured or flushed by army-ant activity, though most of these are inquilines in the ant nest; these and other insects sometimes spend their entire lives hidden in Eciton colonies, often ...
Eciton burchellii is a species of New World army ant in the genus Eciton. This species performs expansive, organized swarm raids that give it the informal name, Eciton army ant. [2] This species displays a high degree of worker polymorphism. Sterile workers are of four discrete size-castes: minors, medias, porters (sub-majors), and soldiers ...
How an army of ants saved zebras from hungry lions in Kenya. Louise Boyle. January 26, 2024 at 12:20 PM ... In warm climates, their arrival “spells almost certain doom” for native insects, ...
One such predator is the army ant Eciton hamatum. In a 100m 2 area on the forest floor, there is a 50% chance of being raided by army ants over an eight-month period. [2] The main defensive mechanism of Bombus transversalis against these attacks is through its nest structure. The colony is covered with a dense canopy of leaves and roots.
In some parts of the world (mainly Africa and South America), large ants, especially army ants, are used as surgical sutures. The wound is pressed together and ants are applied along it. The ant seizes the edges of the wound in its mandibles and locks in place. The body is then cut off and the head and mandibles remain in place to close the wound.
Formerly known as Florida Exotic Plant Pest Council (FLEPPC), the council changed its name to Florida Invasive Species Council (FISC) to retire outdated terminology. [ 172 ] [ 173 ] Three species have been added to Category I since 2019, and Category II now includes four additional species.
