Pokemon Go Wurmple Evolution: Silcoon and Cascoon

With the release of the 2022 Pokemon Go Bug Out event, you're going to be wondering how to evolve Wurmple. Evolving a creature in Pokemon Go usually means feeding them a certain amount of candy, however, Wurmple is slightly more complicated.

Wurmple isn't the most exciting of Pokemon - it's a lowly bug-type Pokemon added in the third generation, a little spiky grub that eventually enters a cocoon form and then becomes something else entirely. However, Wurmple is fairly unique in that you never quite know what you're going to get when you evolve it - it can evolve down one of two unique and specific lines of evolution. On this page, we explain Wurmple evolution, just to dispel any questions you might have about how the mechanic works.

How to evolve Wurmple into Silcoon and Cascoon

As is always the case when a Pokemon has a more complicated evolution, people have questions. And we're here to answer those questions - so let's get it out of the way. Basically, Wurmple can evolve two distinct ways in Pokemon Go:

  • By evolving into Silcoon, Wurmple can ultimately evolve into the Beautifly: Wurmple > Silcoon > Beautifly
  • By evolving into Cascoon, Wurmple can reach the final evolution of Dustox: Wurmple > Cascoon > Dustox

Regardless of in which direction the pair evolve, it'll always cost 12 Wurmple Candy for your first evolution (Wurmple to Silcoon or Cascoon), and 50 Candy for your second evolution (Silcoon or Cascoon to Beautifly or Dustox).

What you're probably wondering, inevitably, is if there's any way to influence this. For instance, you can famously use some names as a little 'cheat code' to get to every single Eevee Evolution in Pokemon Go, but unfortunately, that's not the case here. The little question mark you see next to the Evolve button for Wurmple is entirely random - you can't influence it in any way.

The good news is that there is a 50/50 chance between the two - so while you might get a little unlucky and get a few of the same Pokemon in a row, you'll definitely get both quickly enough. The chance is nowhere near as diluted as with Eevee. Also, the candy costs are cheap - it couldn't be much better or more fair.

Once you get Silcoon or Cascoon, your next evolution is set - Silcoon turns into Beautifly, and Cascoon into Dustox. It's just the first phase that has a random element.
