Gray Hairstreak

One of the most widespread hairstreaks in North America with slate-gray wings and a bright orange spot near its tail. It uses a remarkably wide range of host plants.

💡

Did You Know?

Its caterpillars feed on plants from over 20 different families, making it one of the most generalist butterfly larvae in North America.

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.
