Rosy Underwing

A large moth with camouflaged grey-brown forewings hiding vivid rosy-pink and black hindwings. When disturbed, the flash of pink confuses predators as it drops from its perch.

💡

Did You Know?

Like all underwing moths, it uses a startle display, flashing its bright hindwings then vanishing as it re-covers them.

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.
