Learn more about the Army ant – with amazing Army ant videos, photos and facts on Arkive. Eciton burchellii are terrestrial, although colonies may occasionally bivouac ( temporarily nest) in trees several meters above ground. Army ants need very humid. Eciton burchellii swarms are largely diurnal, whereas other Eciton species may also be found hunting at night. Eciton burchellii swarms take a broad range of.

Eciton burchellii, the swarm raider

Departure calls can be used as cues to tell the other mate where the location of the raid is. Unlike other Hymenoptera species, ants cannot actively thermoregulate through processes such as evaporation, fanning, or incubation. Retrieved 25 April This fuses with burchelili sounds such as an irregular staccato produced in the random movements of jumping insects knocking against leaves and wood.

Suddenly the queen appears in the thickest part. Also, there is evidence that workers from the queen zone cannibalize brood from the other zone when they contact them. Eventually they are abandoned and left to die.

For example, light reflected off of water has waves vibrating horizontally.

A queen will mate when a winged male is discovered by foraging workers and brought back to the bivouac. A few days later the “callow” workers so called because they are at first weak and lightly pigmented emerge from the cocoons. The eggs of Eciton burchellii develop in synchrony and hatch into larvae at the end of the day statary period.


In terms of geographical distribution, this species is found in the Amazon jungle and Central Burchellik.

Eciton burchellii – AntWiki

This page was last edited on 22 Novemberat Eciton burchellii is a species of New World army ant in the genus Eciton. This way, they ensure that there are available resources in their foraging area and they avoid any aggressive conspecific encounters. They have long, pointed, falcate hook-shaped mandibles. Ants, in general, are excellent organisms to study differences in thermal ecology for a number of reasons: For example, if the queen is removed for a few hours at a time, she is ceiton accepted back into the brood-free zone from which she originated, but she is rejected by ecciton belonging to the other burchellik.

I doubt these forms are completely geographically isolated. Their long legs on an elongated body make them appear almost spider-like. Neotropical living in the southern part of the New World.

Pyramid ant Dorymyrmex insanus. Since numerous insects and other small prey can escape the swarm, the frequent raids of the ants do not desecrate an area’s prey reserves. When I first saw a milling burchelii of these dark army ants pushing across the burchellui last month at our lodge in Belize, I did a double-take. But it was T. Army ant conservation There are currently no specific conservation measures in place for Eciton burchellii.


Brown, is a highly specialized and ponderous operation. Journal of Evolutionary Biology. Holldobler and Wilson, New colonies are formed when new queens emerge from their cocoons. The Biology of Social Predation. These kinds of top predators are usually of enormous conservation interest, but unfortunately not ant specialists. The color forms could easily rest on a very small genetic difference, perhaps a single gene. Eciton burchellii are swarm raiders, foraging in a dense fan shaped swarms that can span several meters across, attached to the temporary nest bivouac by a single column that can itself extend over meters.

Army Ants of Darkness: Eciton burchellii parvispinum

In his catalog Bolton was particularly careful about checking names in the original publications. American Scientist77 2: Army ants Dorylinae are characterized by their unique nomadic behavior pattern and purely carnivorous diet SchneirlaSchneirla burchrllii al.

Or is it just the tip of a larger genetic iceberg, such that the dark and light forms are separate, non-interbreeding groups? X Close Image credit.
