Upon evolution, Vibrava gains the ability of limited flight. However, its wings are not fully mature, and are ineffective at flying any significant distance. Although they are not this Pokémon's primary method of locomotion, they are their primary method of prey capture. By vibrating its wings rapidly, it produces ultrasonic waves. These waves are quite powerful, and can cause their prey to faint. Fortunately, these waves usually do no more damage than a headache in humans.
