Butterfree resembles a vaguely anthropomorphic butterfly with a purple body. Unlike true insects, it only has two body segments and four light blue legs. The upper pair of legs resemble small, three-fingered hands, while the lower pair resembles long, digit-less feet. Butterfree has two black antennae, a light blue snout with two fangs underneath, and large, red compound eyes. The red compound eyes at a closer look are revealed to be myriad of tiny eyes. Its two pairs of wings are white with black venation. The two oval scales on a female Butterfree's lower wings are black, but they are white on a male.

The wings of Butterfree are coated with poisonous scales that easily fall off continuously as it flies. If inhaled, it results in several status conditions. It will defend Caterpie from bird Pokémon using this powder. This powder also repels water, enabling it to gather honey even in the rain. Butterfree can use its sensitive antenna to detect the odors of blooming flowers six miles (ten kilometers) from its nest in search of nectar, which it carries with the hairs of its legs. Sometimes, it has territorial disputes with Abuly over fields of flowers. It also consumes sap from trees pierced by Heracros, as seen in the anime. Butterfree is found in temperate forests and jungles, but it has also been observed flying near the ocean as part of its migratory breeding pattern.
