Terravore
From Tardis Wiki, the free Doctor Who reference
Terravore were insectoid creatures that resembled large mechanical mosquitos. The term was always used in the singular form as the Terravore shared a hive mind and were therefore not considered to be individuals. In 2010, they invaded Earth and thousands attacked the London Underground. (AUDIO: The Crimes of Thomas Brewster)
In 2011, a deactivated Terravore was stored in the Vault. (AUDIO: Tales from the Vault) In 2014, Rees used his mind to control this Terravore to help him search for his music box. (AUDIO: The Screaming Skull)
They had extremely limited vision. (AUDIO: The Crimes of Thomas Brewster, The Screaming Skull)
