Observations on the biology and taxonomy of flies found over swarm raids of army ants
High rates of army ant
raids in the Neotropics and implications for ant colony and community structure.
The antbirds have several calls, some to let fellow antbirds know where the army ants
are heading, others to attract mates and still others that are defensive or aggressive to protect turf.
Colony size ranges from a few individuals to over a million in some leaf-cutting and army ant
species to hundreds of millions in some species with supercolonies (Bourke, 1999).
When the front lines encounter spiders, other species of ants, and even scorpions, the army ants
group up, grab the prey, inject it with venom, and pull it apart.
When army ants
use their own bodies to plug tiny potholes in rough trails, the whole colony benefits, a new study has found.
Complaints directed at recent epics like "Troy" for reducing battleground troops to digitized army ants
applies here in spades, resulting in turning what should be a moving and suspenseful war between imperial factions into a kind of video game.
Fisher knew that no ant in Madagascar known to science exhibited this type of aggressive behavior, which is characteristic of army ants
Key words: formicidae, army ants
, Ecitoninae, Morelos, Mexico.
Scavengers, known as the "cleanup crew" in the world of animals, are shown here in stunning full-color photographs of army ants
doing what they do best.
Leaf Cutters cultivate gardens of fungus in order to ensure a steady food supply and make their home in the tropical rainforests of South America, while meat-eating Army ants
migrate through parts of Africa and South and Central America in search of prey.
She leaves him after he tells her to kill the Brazilian army ants
behind their fridge.
Centipedes, army ants
and rattlesnakes were all candidates, along with the jaguar.
The traits that enable a colony of army ants
to find food and set up supply chains to nurture the entire colony, he explained in an interview, can help complex companies find efficient solutions to difficult problems.
For one thing, workers of some army ants
species are totally blind--for example, Eciton burclielli, which produces what perhaps are the most striking and impressive bivouacs--and rely on local pheromone trails and other chemical and tactile signals rather than visual cues (Franks, 1989; Gotwald, 1995).
