After dormant underground for 17 years, billions of cicadas will break ground on the east coast of the United States this summer

As reported by “Newsweek”, the appearance of cicadas has been around for a long time. The scale of criticizing cicadas is absolutely huge. These cicadas may appear in 15 U.S. states, mainly in the East Coast area, but extend to Illinois at the westernmost point. Although these insects are not dangerous to humans, their calls are very loud, which can cause considerable trouble.

These cicadas that have been dormant underground for 17 years are expected to appear in Delaware, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, North Carolina, New Jersey, New York States, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Washington, D.C., but may expand to neighboring states in some cases.

After the cicada pupa emerges from the ground, it will climb on the tree and molten into an adult. Adults have wings and then set out to find a mate. The incredible sound they make is related to the mating process. Once they mate, their lives enter the countdown. Once insects lay their eggs, they die. After hatching, the larvae will live underground for 17 years until they emerge.

The interesting thing about this cicada-except that they live underground for a long time and only appear on the surface for a short time-is that some larvae have formed different cycles. For example, there are more than a dozen specific larvae in the United States alone. Some of them are 17-year cicadas, and there is a 13-year cicada. In addition, there are some annual cicadas, their life cycle is 2 to 5 years, every summer when the temperature reaches a certain level will appear. However, in the coming summer, cicadas in various states of the United States will be more active, because in these states, cicadas that have been dormant for 17 years are ready to appear.
