Ravenous Whiskerpillars are harmless enemies in Pikmin 2. These enemies do not care about the Pikmin, instead aiming for Burgeoning Spiderworts, particularly their berries. They climb atop the plant and begin chewing on the berries, destroying them. After it's knocked off or it's full, it flees for a while, and proceeds to bury underground, making it important to defeat it before it does so. Until it's killed, it will keep returning. Strangely, this enemy does not appear to actually die, as it can be seen squirming while carried.
