2024年7月19日 · Megaponera analis ants have a thick carapace that can withstand mandible attacks from other ants. The leafcutter ant Acromyrmex echinatior uses magnesium calcite to craft a biomineral armor. In Pheidole pallidula ants, smaller workers immobilize their enemy, while the larger “soldier” ants kill them.

Being the largest ants on Earth, army ants, such as African Dorylus queens have the greatest reproductive potential among insects, with an egg-laying capacity of several million per month. Army ant queens never have to leave the protection of the colony, where they mate with foreign incoming males which disperse on nuptial flights .

2011年12月1日 · Among army ants, species of which inhabit warm regions around the world, and a few other groups, such as Asia’s marauder ant, hundreds or even millions of individuals proceed blindly in a tight...

In general, there are two main ways ants conduct these conflicts. [10] On the one hand, some species use specific ants that are more powerful and whose primary function is to fight.

However, one report described Paraponera clavate (Hymenoptera: Formicidae: Paraponerinae), which nest in or near trees that are also their foraging site ...

2023年8月29日 · We formed small armies of 20 meat ants, and opposed them in the lab to increasingly large armies of up to 200 Argentine ants. These battles took place either in simple arenas (featureless plastic containers) or complex arenas (the same containers with narrow wooden strips glued to the floor).

Despite the apparent evenness of the battle, army ants possess a significant advantage due to their social unity. Individually unimpressive, they overwhelm their victims with sheer numbers, often leading to the destruction of the prey colony. Interestingly, army ants …
