Wurmple (Japanese: ケムッソ Kemusso) is a Bug-type Pokémon. Wurmple will evolve into either Silcoon or Cascoon starting at level 7 depending on its personality value. As personality values cannot be influenced or seen by the player, what a given Wurmple will evolve into is essentially random. From there, the Silcoon or Cascoon will evolve again starting at level 10 into Beautifly or Dustox respectively.


Wurmple is a small, caterpillar-like Pokémon. Its body is mainly red with a cream underside and face. It has large yellow eyes with dark pupils. It has one sharp yellow stinger on its head and two of them on its rear. It has a tall, erect, red spine behind its forehead and a similar, smaller spine behind that. It has small spikes running down the top portions of its body and five pairs of stubby white limbs.

Wurmple has suction pads at the tips of its feet, which allow it to cling to glass or tree branches without slipping. It can spit a white silk that turns gooey when exposed to the air. It can release poison from its tail spikes, which can weaken and poison foes. Wurmple lives in forests. It eats leaves and pulls bark off trees to feed on the sap.

  • Wurmple is the only Pokémon whose branched evolutions evolve further. All other Pokémon with a branch in their evolutionary line either evolve once before the branch or do not have any other evolutionary event besides the one which is branched.
  • Wurmple shares its species name with Caterpie. They are both known as the Worm Pokémon.
  • Wurmple is the only Pokémon whose evolution is directly influenced by its personality value. Pokémon whose evolution is influenced by their gender are also technically evolving based on their personality value, although unlike Wurmple, their determined evolution can be known in advance.
