Doryline ants have colonized the Americas on two independent occasions. The first event gave rise to a speciose and ecologically highly successful clade that includes the New World army ants. The first picture shows one representative, a large worker of Labidus coecus.

The second event occurred much later, and resulted in a few inconspicuous species in the genus Syscia. The second image shows the queen of Syscia madrensis with two of her daughter workers from Arizona’s Chiricahua Mountains.

Now it turns out that this genus is actually MUCH more diverse in the New World than previously thought. Based on extensive sampling in Central America, a new paper by and increases the number of known species from 3 to 57! Unbelievable really!

The workers of some army ant species vary dramatically in shape, size, color, and even behavior. Here is the full range of the Eciton hamatum worker caste - from large soldiers with hook-shaped mandibles (upper left) to the smallest workers that tend to the queen’s eggs (lower right).

Jack Longino reviews "Army Ants" in Current Biology:

Daniel Kronauer sits on a folding stool in the dawn rainforest of La Selva Biological Station in Costa Rica. He is watching a pulsing mass of army ants, a ‘bivouac’, as the first rays of sunlight strike its surface. As he describes it, a shiver of activity spreads through the bivouac: the beast ...

Siafu snafu: Army ants are infamous social hunters that can overwhelm prey much bigger than the individual ant. Here, Dorylus molestus driver ants (aka “siafu” in Swahili) are butchering a large slug at Mount Kenya 🇰🇪. From Chapter 3 of the Army Ants book: amzn.com/067424155X
