Wurmple is a Bug type Pokemon introduced in Generation III. 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. Take a look below for 25 fun and fascinating facts about Wurmple.
