Pomarius

From Tardis Wiki, the free Doctor Who reference

Pomarius was a planet famed for its beautiful orchards. It was overrun by Cyborg Spiders constructed and programmed to help protect the crops from attack by fruit flies. The spiders became out-of-control and covered the planet in their metal web trapping all who touched them including the TARDIS and a local farmer Heldan. (COMIC: The Steel Web)
