What are periodical cicadas?
Periodical cicadas, found in the eastern United States, have an extraordinarily long life span, most of which is spent underground. These cicadas remain in an immature form called a nymph for over 99% of their lives. During this time, they sustain themselves by consuming xylem fluids extracted from the roots of deciduous trees.
When do cicadas emerge?
After 13 or 17 years, depending on the species, the mature cicada nymphs emerge from the ground in immense numbers. This event takes place between late April and early June, with the exact timing varying based on the latitude of the location. The emergence is synchronized, with all the nymphs coming out at roughly the same time.
Once above ground, the adult cicadas have a relatively short lifespan of only four to six weeks. This brief adult stage contrasts sharply with the exceptionally long developmental period they undergo as nymphs underground.

About Periodical cicadas
The term periodical cicada is commonly used to refer to any of the seven species of the genus Magicicada of eastern North America, the 13- and 17-year cicadas. They are called periodical because nearly all individuals in a local population are developmentally synchronized and emerge in the same year. Although they are sometimes called "locusts", this is a misnomer, as cicadas belong to the taxonomic order Hemiptera, suborder Auchenorrhyncha, while locusts are grasshoppers belonging to the order Orthoptera. Magicicada belongs to the cicada tribe Lamotialnini, a group of genera with representatives in Australia, Africa, and Asia, as well as the Americas.
