The Ravenous Whiskerpillar is an enemy in Pikmin 2. These enemies are not harmful to the Pikmin, but are dangerous to the Burgeoning Spiderwort plants. They will eat the berries on the plants, which are necessary to make sprays. When confronted, they will drop off the plant and burrow into the ground. Strangely enough, when killed, they don't seem to be dead; carrying them will make them squirm and emit more of their hissing. The in-game Piklopedia states that they are a larval form of another creature, but the game series does not have an adult form for it yet.
