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.

Springfly

A spring-emerging stonefly of fast-flowing European streams. Nymphs are active hunters that pursue prey among streambed gravels.
