Primeval - Season 5 Episode 4 The Prototype

The team learn the truth about New Dawn when Connor creates an artificial Anomaly in the ARC, and trouble soon erupts when the Anomaly unleashes swarming, carnivorous beetles from the future into the ARC, which trigger the lockdown but threaten to burrow out and swarm onto the modern world. The situation is only exacerbated when the beetles trigger Jess' deadly allergy to insect bites, and when Philip threatens to incinerate the entire ARC to stop the beetles.
