“This is the only spot where we have cicadas on a 17 year cycle.”īut land development that reduces valuable woodlands and natural areas could impact the future of Brood X for hundreds of years. “They really are a special treasure for the entire planet,” said Owens. A fragile balanceĪlthough they may not sound like the kind of neighbors you would want to move in permanently, Brood X offers us a short glimpse into something incredible - and incredibly fragile. It is unlikely that this process will cause any severe permanent damage to local trees or any damage to crops in New Castle County. For trees of concern, homeowners can use netting to cover and prevent female cicadas from accessing the branches. Unless they are recently planted, small or very weak, most trees should sustain only minor cosmetic damage. The average person will only notice this occurrence when small tree branches snap and hang down from the tree - a phenomenon known as “flagging.”īut homeowners don't necessarily need to worry about their trees. In true rockstar fashion, “they come out and have a three week long party in which they drink plant fluids, mate and lay eggs,” said Kunkel.Īs the party comes to a close, the female cicada uses a special serrated body part called the ovipositor to make small cuts into thin tree branches and lays her eggs inside.
Despite spending nearly two decades underground, each cicada will only live above ground for approximately four weeks. Whether you want to simply hear their deafening chorus or to fry them up as a crunchy protein-filled snack (yes, that’s a thing), you’ll need to hurry. “Some of the Brood X species sound like a buzz saw while others make sound more akin to ‘whooo-ooh.’ ” The cycle continues “It is higher pitched, almost a white noise that drowns out conversation,” said Owens. Still, many Delawareans will experience louder cicada songs than usual. Luckily, though, they won’t quite reach the 105 to 110-decibel noise of your typical rock concert. Centers for Disease Control and Prevention compares to a car horn at 16 feet. The first time I saw it was in the eighties and I was very much into fishing and using them for finishing bait.The first time I saw a big, massive group of insects crawling up the trunk of a tree, it was just incredible.”Īs if that’s not rock-and-roll enough for you, the Brood X cicadas also use what is known as a tymbal organ to create a 100-decibel sound that the U.S. “It's pretty cool to see that massive number of skins everywhere.

“These insects come crawling up out of the ground in mass and start clinging to the sides of buildings, fences, whatever and popping out the back of the nymphal skin to become adults,” Kunkel said. “They can be so abundant the shed skins form piles under trees.” But Brood X is by far the largest and all-encompassing of the county,” explained David Owens, a University of Delaware Cooperative Extension entomology specialist. “There are other broods in our area that occasionally may be seen. While cycles of 13 and 17-year periodical cicadas pop up throughout the eastern United States in different years, this particular brood is notable as northern Delaware’s most significant in population size and geographic spread. Bush had not yet secured his bid for a second term as president of the United States.Īt 17 years old, they have spent their entire lives feeding on deciduous tree roots in the soil below undisturbed patches of hardwood trees.
The last time these cicadas saw the sunlight, Greece hosted the Summer Olympics, Lance Armstrong won his sixth Tour de France title and George W. This summer, residents of northern Delaware will listen to the hip new sound of Brood X, the latest emergence of periodical cicadas that only occurs every 17 years.
It’s the roaring twenties again - at least if you live in New Castle County.
