Why do moths turn to dust when you kill them?

The wings of butterflies and moths are made up of really small scales that help the moth to fly. The scales are so small that when you rub or crush the moth's wings, these protective scales crumble and fall apart like dust. The scales are also responsible for the color on a butterfly's wings!
