Epomis Ground Beetle

A beetle whose larvae lure and devour frogs — a rare case of predator-prey role reversal. The larva waggles its antennae to attract an amphibian, then latches on and feeds.

💡

Did You Know?

This is one of the only known cases where an insect larva regularly preys on vertebrates — the larvae have a near 100% success rate against attacking frogs.

Bordered Mantis

A large green mantis with two prominent dark eyespots on the inner surfaces of its forelegs. It uses these spots in its threat display by spreading its legs wide. It is common in South American forests.

💡

Did You Know?

The twin eyespots on its forelegs create the illusion of a face with two large eyes when displayed to predators.
