They don't really have the same body part, exactly. They have body parts which function similarly, but which are not related structures. This is an example of convergent evolution. This occurs when two unrelated groups of animals evolve similar structures to accomplish the same function. Another example of convergent evolution is the wings of bats, birds, and flies. Their wings are completely unrelated and, in the case of flies, obviously dissimilar. But the wings in all three animals enables those animals to fly.
that would be the wings, like all flying insects that make a buzzing sound.
