This episode focuses on the adaptations of arachnids and insects. The search starts in the backyard at night time, exploring for spiders who are nighttime builders. These backyard predators are described as astonishing architects that design and build intricate silk webs with safety lines, places where they anchor themselves to wait for unsuspecting insects. Their amazing adaptations: speed, size, silk webs, and venom, make them efficient predators. In the morning the exploration continues with a look at several insects living above and below the water's surface (mosquitoes, whirligig beetles, caddis flies, and dragonflies). More amazing adaptations are introduced including incomplete metamorphosis, eye development, and remarkable breathing apparatus.
