South American Giant Hornet

A large nocturnal social wasp that builds exposed paper nests under tree branches. Unlike most wasps, it is primarily active at night, using its large compound eyes for navigation. Colonies can contain thousands of workers that become highly agitated if disturbed.

💡

Did You Know?

It is one of the few truly nocturnal social wasps in the world, hunting and foraging under starlight and moonlight.

Parasitic Acacia Ant

A cheater species that occupies acacia thorns but provides little defensive benefit to the host tree. Unlike mutualist acacia ants, it does not attack herbivores or clear competing vegetation.

💡

Did You Know?

It exploits the mutualism by taking food from the acacia without reciprocating with defense, essentially freeloading.
