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 ...
There are ant-mimicking staphylinid beetles, shaped like the ants they follow, that run with the swarm, some of them preying on stragglers or other insects injured or flushed by army-ant activity, though most of these are inquilines in the ant nest; these and other insects sometimes spend their entire lives hidden in Eciton colonies, often ...
Leiningen decides to advance this plan by a month when he hears from the local commissioner of a potential attack by an army of ants (marabunta), as he does not wish her to be harmed. As she awaits the boat to take her back to the United States, they learn that legions of army ants - the "marabunta" - will strike in a few days' time. Leiningen ...
Army ant bivouac. A bivouac is an organic structure formed by migratory driver ant and army ant colonies, such as the species Eciton burchellii.A nest is constructed out of the living ant workers' own bodies to protect the queen and larvae, and is later deconstructed as the ants move on.
Although he studied many aspects of army ant biology, he particularly focused on the animals associated with the ants and especially mites which live on the ants. He was well known for his photography of army ants, with his photographs appearing in over 100 publications, and he used his video footage to create two DVDs.
Each ant merely follows the ant in front of it, which functions until a slight deviation begins to occur, typically by an environmental trigger, and an ant mill forms. [2] An ant mill was first described in 1921 by William Beebe, who observed a mill 370 m in circumference. [3] It took each ant two and a half hours to make one revolution. [3]
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. Rather, it forages in columns, often in trees and preying exclusively on the larvae of other social insects.
