Butterfree (Japanese: バタフリー Butterfree) is a dual-type Bug/Flying Pokémon. It evolves from Metapod starting at level 10. It is the final form of Caterpie.
Butterfree resembles a vaguely anthropomorphic butterfly. Unlike true insects, it only has four legs, which are a pale blue color. It has a nose-like structure, which is a similar color. The coloration of a Butterfree’s body is a darker purple-blue. It has large veined wings, which are white with black markings. These markings can help distinguish male and female individuals. It has large compound eyes that tend to be a reddish color. Like members of the order Lepidoptera, Butterfree’s two pairs of wings are covered in fine scales. Its legs are covered in fine hairs, which aid in the collection of honey.
