Across 15 states in the United States, trillion beels will emerge immediately after 17 years underground, scientists say, despite a sign of climate change, nature continues.
The two scientists, working in the east coast state of Maryland, walk through the backyard of the suburbs, Michael Roop and Paula Sreesanth, to find their anecdote: A Sikda Astika.
Anthologists at the University of Maryland find at least seven cicadas in a third of a square foot of dirt – a shameful rate of one million per acre. A nearby yard earns rates close to 1.5 million.
In a few days, most of the week, Broad X’s Cicadas (Roman numerals for 10) exclusivity will be published under 17 years of ground. Periodic cicadas have many broods that appear on a strict schedule in different years, but it is one of the largest and most notable. They will be in 15 states from Indiana to Georgia to New York; They are now coming out in populations in Tennessee and North Carolina.
When the whole brood is raised, the backyards may look like undulating waves, and the bug chorus is louder than the lawnmower.
Cicadas will come out most of the evening to try to avoid everything they want to eat, which comes out of a hole in the ground. They will try to climb trees or anything vertical, including roop and shrubs. Once off the ground, they spread their skins and try to survive at that risky stage before becoming the dinner of many critics, including ants, birds, dogs and cats.
It is a bizarre phenomenon of a nature characterized by sex, competing against death, evolution, and sounding like the soundtrack of a bad science fiction movie.
Some people may be deported. Psychiatrists are anxiously calling on entomologists about their patients, Sreusbury said. But scientists say the arrival of Brood X is a sign that, despite pollution, climate change and dramatic biodiversity reductions, some are still true with nature. And it’s quite a show.
Roop describes Sika’s life with all the actions of a blockbuster in Hollywood.
“You’ve got an animal that has been in existence for 17 years, like a cavid, sucking on the sap of isolated underground saplings, isn’t it? In the 17th year, these teenagers will come out of the world without billions. The planet is going to try for everything that wants to eat them at this critical time of night when they are just trying to grow up, they are just trying to become adults, that skin has fallen off, they will get wings, get on tritops, escape from their predators. ” He says.
“Once in Tritops, hey, everything will turn into romance. It is only sung by men. It’s going to be a big boy band out there, when men try to hate these women, try to convince that special someone that she should be the mother of her aps. She is going to perform, sing. If she likes it, she’s going to click on her wings. They’re going to have some wild sex on the trip.
“Then he will go to the small branches, get the eggs. Then in a few weeks it will be over. They are breaking down. They are going to fertilize very well the plants from which they originally originated. After six weeks, the tiny nymphs will grow to 60 feet taller than tritops, bounce twice, land, and return to the ground for another 17 years. ”
“It’s the most clever life cycle of any creature on the planet,” Roop says.
The United States is the only place in the world to have periodic cicadas that have been underground for 13 or 1 year, says John Cooley, an entomologist at the University of Connecticut.
When the groundwater temperature reaches 4 degrees Fahrenheit (1.8.6 degrees Celsius), bugs only emerge in large numbers. This is the first time this has happened on the calendar in recent years due to climate change, said ecologist Jean Kritsky. Before 1950 they were grown at the end of May; Now they are coming out a few weeks ago.
Although Maryland and Ohio have some early bugs, soil temperatures have dropped to 60 degrees Fahrenheit. So Roop and other scientists believe that the big rise is a few days away – a week or two, at most.
Sikadas who come out early do not survive. They are quickly eaten by predators. Cicadas has developed a basic survival strategy: irresistible numbers. Roop said many of them are eaten when they come up together, so some can survive and reproduce.
This is not an attack. The cicadas are here for the whole time, silently feeding the tree roots underground, not sleeping, just slowly waiting for their body clock to tell them that the time has come for them to come out and breed tell they have been in the United States for millions of years, much longer than humans.
“When a single bar makes a horribly horrible mistake,” Cooley said, when there was a noise like 105 decibels. There are three distinct cicada species here and each has its own mating song.
These are not locusts and the only damage to their plants is the young trees, which can be given nets. Trees work better one year after a large batch of cicadas because dead bugs act as fertilizer, Kritsky says.
People are afraid of the wrong insects, says May Berenbaum, an entomologist at the University of Illinois. Mosquitoes kill more people than other animals because of malaria and other diseases. Yet some people are really afraid of the rise of Sikda, he said.
“It simply came to our notice then. Also, they smell bad when they die in large numbers, ”says Berenbaum. “They really disrupt the meaning of our order.”
Others, however, are fond of cicadas – and even use recipes like a cookbook from the University of Maryland. And scientists like Cooley have a real beauty to their life cycle.
People, this is a feeling-good story. That’s really and we need more of it in a year, ”he says.“ When they come out, it’s a great sign that the forests are in good condition. Everything is as it should be.
