Horntail Wasp

A large wood wasp that injects symbiotic fungus into trees along with its eggs.

💡

Did You Know?

The injected fungus softens the wood to make it digestible for the larvae.

Slave-Maker Ant

A tiny North American slave-making ant that raids colonies of closely related Temnothorax species. Workers have saber-like mandibles used in raids. Enslaved workers eventually perform all domestic tasks while raiders focus solely on conducting new raids.

💡

Enslaved Temnothorax workers sometimes rebel by destroying the slave-maker brood they are supposed to rear, reducing the raiding colony's future workforce.
