"The struggle to break out of the cocoon develops the butterfly so it can fly. Without that adversity, the butterfly would never have the strength to achieve its destiny". So, too, with our own adversity.
Closeup of the wing of a butterfly, Protboe calidonia, showing its arrangement of wing scales. The scales are attached to the wing membrane by short stalks, which fit into tubular sockets. The colour of the wing is determined by the pigmentation of the scales and also by diffraction of light off the surface of each scale.
