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]
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 .
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 ...
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.
This is a list of extant snakes, given by their common names. Note that the snakes are grouped by name, and in some cases the grouping may have no scientific basis. Contents:
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 ...
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.
Ants – social insects with geniculate (elbowed) antennae and a distinctive node-like structure that forms a slender waist. Ants are of the family Formicidae and evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago, diversifying after the rise of flowering plants.
