Amazon Ant

A slave-making ant that raids colonies of Formica ants to steal pupae, which then emerge as workers in the Polyergus colony. The sickle-shaped mandibles of Polyergus workers are adapted for combat but useless for foraging or nest maintenance. They depend entirely on their captive workers for food and brood care.

Did You Know?

Without their enslaved workers, an entire colony would starve because their sickle-shaped jaws make them incapable of feeding themselves.

South American Wattle Sawfly

A shiny black argid sawfly that feeds on wattle (Acacia) trees. Larvae are green with dark dorsal markings and can cause significant defoliation.

Did You Know?

This species is one of the relatively few argid sawflies found in Africa, where the family is less diverse than in other continents.
