Prehistoric Park (2006) - 1x05 - Giant Insects

Nigel Marven embarks on an operation that would make most people's toes curl as he attempts to rescue giant creepy-crawlies from the hostile habitats of 300 million years ago. On the way to Scotland, the explorer encounters a swarm of enormous dragonflies and a 10ft-long millipede. Meanwhile, the team at the park try to breed the sabre-toothed cats.
