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]
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 ...
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]
Ants (family Formicidae in the order Hymenoptera) are the most species-rich of all social insects, with more than 12,000 described species and many others awaiting description. [1] Formicidae is divided into 21 subfamilies , of which 17 are extant and four subfamilies are extinct , described from fossils .
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.
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 ...
They are unique to the subterranean foraging D. laevigatus; other species of driver ant and army ant prefer a constantly changing system of raids with columns alternating directions. [citation needed] These surface foraging ants also prefer to mix castes in their raids, with large and small workers moving together to search for prey.
The red fire ant, one of the world’s most invasive species, has been found in Europe for the first time, according to a new study published Monday. The red fire ant, one of the world’s most ...
