17 Year Cicada: 17 Year Cicada Swarm - There exist 6 species of periodical cicadas: with a 17-year cycle (3) and with a 13-year cycle (3). But all those three species of each life-cycle group differ in size, color, and sound. The 17-year-old cicadas tend to locate in the North, while the 13-year-old ones - in the South. Nevertheless, both types may emerge in the same forest.

At last, nymphs exit from the ground and crawl up weeds, tree trunks, or other upright objects. Now adults emerge by leaving behind their nymphal skins within an hour. The newcomers look now soft and white. But their exoskeletons either harden or become darker.
