In this episode, we see some of the largest insects in the world. The nocturnal giant African millipede, the oldest known land creature, is a crawling composter scavenging in caves. The giant prickly stick insect lives on leaves in the rain forest, perfectly camouflaged. The tropical forest peacock mantis is named for the eye patches on its wings. Bluberus giganteus, a giant cave cockroach is one of the largest in the world. And stag beetles intimidate competing males with their huge jaws.
