Stone mite

Stone mites were a stone-and-metal-eating species of non-sentient insect that originated on the planet Coruscant before spreading to various locations across the galaxy. The mites lived in trios that shared a single central shell, with each mite's head emerging from a different corner and a feeler-tail capable of delivering an electric shock located between each pair of heads.

An undetected stone mite infestation during the Orleon Belt Grand Slalom Finals resulted in several racers and their vehicles being devoured while the event was being broadcast live across the galaxy. During the Galactic Civil War, stone mites also infested the Millennium Falcon, a YT-1300 light freighter piloted by Captain Han Solo and the Wookiee Chewbacca, who were forced to remove the infestation and repair the damage it caused.
