It is a cyclical phenomenon that repeats itself every 17 years. Millions upon millions of cicadas come out of the earth. All at the same time, in an almost nightmarish show. Yes, the cicada invasion of the United States is coming.
You are of the kind Magicicada septendecium. They are known as “periodic cicadas”. You spend almost two decades underground. Then they come to the surface to mate and finish their maturation. At a temperature of around 17 ° C, the nymphs sit in the trees to shed their skin. They are preparing to mate. And then come the annoyances. To attract partners, the males make a deafening noise. It’s kind of like that of a large-volume motorcycle, a high-pitched soundtrack that is extremely annoying for nearby cities.
This year this invasion of cicadas will be particularly significant. Billions of specimens are expected to soar through the sky over much of the country’s east coast. The unique event is called Brood X (Generation X).
“Generation X is here! We saw cicada holes in the ground and remnants of moults clinging to trees. They appear and move, calling and mating. And all according to his 17-year strategic plan ”. This is how a publication of the Twitter account from the National Mall, from the United States Park Service.
Cicadas are not harmful to humans. Not for pets, gardens or plants. Scientists say there are between 3,000 and 4,000 species of these insects. But periodic cicadas seem unique. Even so, many entomologists ask themselves the following questions: What have these insects been doing underground for so long? What do they feed on? Why do they live in such long cycles? Why do they sync to show up and mate?
The first American settlers first encountered periodic cicadas in Massachusetts. The sudden appearance of so many insects reminded them of the biblical plagues of locusts. One of the common names of this species is “pharaoh cicada”.
The invasion of the cicadas in the United States is approaching. For a few days, his hoarse rumor will be a nuisance. But then they rest again. Up to 17 more years.
