Pokémon GO Wurmple bug has a branched evolution tree. This means that this Pokémon can either evolve into a Silcoon bug then into a Beautifly bug , or it can evolve into a Cascoon bug, then Dustox bug poison in Pokémon GO.
This kind of branch evolution is already present in the game when the Second Generation was released. We can compare this branch evolution from that of Eevee. The evolution mechanism of Wurmple is still being researched but there are a few running theories:
- it evolves randomly
- it evolves depending on the time of day
- it evolves depending on it’s highest IV
Position in the meta game
Wurmple has a single role to fill in Pokemon GO: mass evolution fodder. Similar to how Weedle and Pidgey were used in Generation 1, Wurmple and Whismur are the 12 Candy evolution line that will be abused for mass evo XP grinds.
In a competitive sense, Wurmple or his family has no place in raids / gyms or any type of PvP.
Beautifly and Dustox Moves in Pokémon GO
Pokémon GO Beautifly and Dustox have a pretty similar move pool to choose from, since they both evolve from Wurmple. If you’re looking for a good Beautifly go for Infestation / Bug Buzz, and for Dustox go for Confusion / Sludge Bomb.
They share the following moves and introduce two separate moves per branch:
- Struggle bug (quick)
- Bug Buzz bug (charge)
- Silver Wind bug (charge)
Moves reserved for Beautifly:
- Infestation bug (quick)
- Air Cutter (charge)
Moves reserved for Dustox:
- Confusion psychic (quick)
- Sludge Bomb poison (charge)

In the anime
In the cartoon series, May and Jessie caught their Wurmple on the 288th episode of the Pokémon series (Advanced Generation: Episode 14) titled “All in a Day’s Wurmple”. May’s Wurmple evolved into a Silcoon on the same episode that Jessie’s evolved into a Cascoon on the 298th episode of the Pokémon series (Advanced Generation: Episode 24) titled “All Corphish Out of Water”. Funny enough, Silcoon evolved into a Beautifly and Cascoon evolved into a Dustox also on the same episode in the series – on the 302nd episode of the Pokémon series (Advanced Generation: Episode 28) titled “Seeing is Believing”.
