Bug-type Pokémons are characterized by their fast growth. In general, they don't take long to evolve. They live primarily in or near the woods, and some of them are really difficult to observe because they live in the tree tops, where they nest. Most Bug-type Pokémons are also secondary Flying-type Pokémons, which makes them more resistant to Flying-type and Grass-type attacks. However, they are also more susceptible to Rock-type attacks.
These Pokémons usually have vivid colors and a stoic and cheerful personality. Most people think that these characteristics are a personification of the beauty of nature.
