Zarbi
From Tardis Wiki, the free Doctor Who reference
The Zarbi were a insectoid species native to Vortis. Resembling giant ants, they were used by the Menoptera as cattle until the Animus arrived and took control of them, forcing them to fight their former masters. They reverted to their original nature after the Doctor, Ian Chesterton, Barbara Wright and Vicki defeated the Animus. (DW: The Web Planet)
