Giant Wasp

The Giant Wasps were an insectoid species of giant wasps associated with the Quarks.

History
The Quarks attempted to use Giant Wasps to attack the Second Doctor and Jamie McCrimmon on Gano, but the creatures attacked the Quarks instead. (COMIC: The Killer Wasps)

The Sixth Doctor encountered them on Earth, in 1999. (PROSE: Millennial Rites)

A film adaptation of H.G. Wells' The Time Machine, which according to the Sixth Doctor "hadn't even been bad enough to be good", featured Giant Wasps and Quarks. (PROSE: Synthespians™)

Behind the scenes

 * The Monster Files episode Vespiform had Jack Harkness mentioning unconfirmed rumours of a war between Quark rebels and Vespiforms. As the Vespiform in The Unicorn and the Wasp was memorably referred to by Donna Noble was "a giant wasp", it is obvious that the webcast's association of Quarks with the Vespiforms was an allusion to the use of these Giant Wasps as minions by the Quarks. However, whether this intended to show that the two species are one and the same in-universe is somewhat unclear.
