Caterpie (キャタピー Kyatapī), known as the Worm Pokémon, are larval Pokémon found in the wild early in the Kanto and Johto regions. In main series Pokémon games set in these regions, Caterpie are among the earliest and easiest Pokémon species caught by players, as they are very weak. They can be evolved into their cocoon-like Metapod form and eventually into the butterfly-like Butterfree form. Caterpie resembles a green caterpillar with yellow ring-shaped markings down its body. Its most notable characteristic is the bright orange antennae on its head. These and the large eye-shaped markings help to startle predators. Their green bodies are useful for camouflage in foliage, their eyes are patterned to scare away predators, their suction-cup feet allow them to climb any surface, and the osmeterium on their heads can project a horrid stench to repel predators. It bears a resemblance to the spicebush swallowtail caterpillar. more...
