Tetramite

Tetramites were small insects that travelled in swarms. They liked Breegus nectar and, as the swarm was invincible, the nectar was often used as a distraction. They also could not go near water. The concept and idea of them bore a lot of resemblence to the Tumfoids, which were distracted by Gelatonium, yet they were invincible. If Ratchet even touched a swarm of tetramites he would lose a large portion of his health. Collectively, they could kill Ratchet after contact in under five seconds. In Ratchet and Clank Future: A Crack in Time, they were frequently used to eat vines blocking Ratchet or somebody else's way. Breegus nectar could be shot at them using the Omnisoaker.

Behind the scenes
While spelt "Tetramite" in-game, the Ratchet & Clank Future: A Crack in Time Signature Series Strategy Guide had the spelling "Tetramyte".

Trivia

 * The Tetramites bore a strong resemblance to "The Swarm" from another Insomniac game, Resistance 2. It was revealed in the Insomniac Moon that their sprites were in fact grounded versions of The Swarm.
 * The Tetramite swarms had a habit of how they devoured anything and also had a strong resemblance to the scarab beetles in the movie "The Mummy".
 * If Ratchet got caught in a swarm, the Tetramites also lowered his jumping ability.
 * As troubling as they are, Tetramites are only found on 4 levels: Lumos, Zanifar, Agorian Battleplex, and the Insomniac Museum.
