Giant wasp

A giant wasp was, in Donna Noble's words, "a wasp that's giant, (…) flippin' enormous".

Vespiforms were an example of giant wasps. (TV: The Unicorn and the Wasp) A seemingly-unrelated species known simply as Giant Wasps were long-time minions of the Quarks, (COMIC: The Killer Wasps, PROSE: Synthespians™) rebels from whose civilization may also once have been at war with the Vespiforms. (WC: )

Behind the scenes

 * Although this seems to be the intended implication of the mention of a conflict between Quark rebels and Vespiforms in Monster File: Vespiform, whether the Vespiforms and the Giant Wasps are the same species of giant wasp, or simply two similar but unrelated species who both happened to have contacts with the Quarks, has never been officially clarified.
