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.
Western Cicada Killer
A massive solitary wasp of the American West that hunts cicadas to provision its underground burrows. It is slightly larger and paler than its eastern relative.
Did You Know?
Despite its intimidating size, it is generally docile toward humans and males cannot sting at all.
