This is a very fine example of a dewbow on a spider's web -- it's simply a rainbow in dew drops. Like all bows, a dewbow is formed when light refracts and reflects internally inside drops of water. In this case, instead of rain drops, the dew drops are responsible for the optics. This dewbow is especially vivid. It even hosts supernumerary bows, which are faint, colored arcs just inside and near the top of the primary bow.
