The beautiful insect shown here is a planthopper nymph. During the span of time after it hatches and before it becomes fully mature, the planthopper nymph secretes a waxy substance from its abdomen that gives its tail the look of a colorful fiber optic display. It is both a defense from predators who are somewhat hypnotized by the effect, as well as a way to facilitate a gliding movement as they jump, as seen in the video below. There are a number of species of planthopper nymphs, with a variety of different tails. The photos and video above and below show a few varieties. See additional photographs here. -Via The Presurfer
