Cascoon (Japanese: マユルド Mayuld) is a Bug-type Pokémon. It evolves from Wurmple depending on its personality value, starting at level 7, and it evolves into Dustox starting at level 10.
Cascoon is very similar to Silcoon in design, being a cocoon-like Pokémon with two red eyes and limbs to attach itself to tree branches. However, it has a slightly darker, more purple coloration.
