The Neotropical army ant Eciton burchellii has an estimated 350 to 500 animal associates, the most of any one species known to science. [31] It has been speculated that the nocturnal foraging of some army ant species is done to reduce kleptoparasitism by birds, since the bird kleptoparasites of army ants are diurnal. [12]
All species within the three army ant subfamilies have similar behavioral and reproductive traits such as, obligate collective foraging, nomadism, and highly modified queens called dichthadiigynes. [6] Aenictogiton or army ants never forage or hunt alone, they instead use leaderless, co-operative mass of ants to overwhelm their prey all at once.
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 ...
An army of invasive ants has been so disruptive to a Kenyan ecosystem that it has changed the hunting habits of a pride of lions.. The big-headed ant species, which originated on the island of ...
The most predominant and well-known species is Eciton burchellii, which is also more commonly known as the army ant and is considered the type species. Eciton burchellii and Eciton hamatum are the most visible and best studied of the New World army ants because they forage above ground and during the day, in enormous raiding swarms.
Driver ant queens are the largest ants on Earth and have the greatest egg-laying capacity among insects, laying several million eggs each month. [11] Several species in this genus carry out raids on termitaria, paralyzing or killing termites and carting them back to the nest. [12] Colonies of driver-ant species have only one queen. [13]
Dorylus laevigatus is a member of the army ant genus Dorylus, or Old World army ants.More specifically known as "driver ants", the genus Dorylus is abundant throughout Africa and stretches into tropical Asia, where D. laevigatus is primarily found.
Eciton hamatum is a species of army ant in the subfamily Dorylinae; it is found from Mexico to central Brazil and Bolivia.The species differs from Eciton burchellii, in that it does not fan out into the underbrush when foraging.
