Life in the Undergrowth: Episode 4 covers the special relationships between invertebrates with plants or other animals. Included are: aphid-herding ants, gall-inducing insects, and parasitic relationships such as a wasp grub carried by an orchard spider, fairy wasp eggs laid inside eggs of water beetles, and methoca, an ant-like wasp, which paralyzes and then implants a tiger-beetle larva with its eggs.
