The Cl'cli'cl were a race of insectoid humanoids who lived within the borders of the Romulan nation-state, the Romulan Republic in the mirror universe. They were one of several alien races the mirror Romulans were determined to wipe out. (Decipher RPG module: Through a Glass, Darkly)

It is unknown if the Cl'cli'cl have any similar existence in the primary universe.
