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]
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 ...
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 ...
About 50 of the approximately 200 species of antbirds specialize in preying on insects fleeing the ants, getting up to half their food this way. Some of these birds actively check army-ant bivouacs each morning and follow the foraging trail to the swarm front, where they take positions based on their species' relations in a dominance hierarchy.
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]
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 ...
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.
