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 ...
Eciton is a New World army ant genus that contains the most familiar species of army ants. 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.
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.
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.
Formicoids include such widespread and species-rich subfamilies as Myrmicinae, Formicinae and Dolichoderinae, as well as the army ants . Non-formicoids comprise five "poneroid" subfamilies ( Agroecomyrmecinae , Amblyoponinae , Paraponerinae , Ponerinae , and Proceratiinae ), Leptanillinae , about which little is known, and Martialinae , the ...
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 .
Eciton mexicanum is a species of New World army ant in the genus Eciton. Present from Mexico to throughout Costa Rica and northern Argentina, it is found in dry and wet forests in sea level to montane areas. Raids always occur in columns, tending to be usually nocturnal but are sometimes also encountered during the day. [2]
