WASHINGTON 鈥� They have spent close to two decades buried underground, waiting for the right moment to emerge 鈥� before pouring forth by the billions, filling the air with an ear-piercing racket and covering walls and floors from the US east coast to the Midwest.
No, it鈥檚 not a horror film 鈥� well, not exactly 鈥� but rather the regular, if very infrequent, arrival of the cicada, a thumb-sized insect with alarmingly wide-set eyes and membranous wings.
Their unnerving arrival is as spectacular as it is rare. Every 17 years, these 鈥減eriodical鈥� cicadas emerge just long enough to mate, lay eggs鈥� and die.
鈥淚t was like science fiction,鈥� said Melanie Asher, who lives in the Washington suburb of Bethesda, Maryland and who clearly remembers the insect invasion that hit the area in 1987, when she was a child.
鈥淭he floors were covered with cicadas just dropping dead,鈥� she said.
鈥淚鈥檓 not scared of bugs (but) it was freaky 鈥� it was very much otherworldly.鈥�
This year the cicadas are expected to arrive in May, or possibly a few weeks earlier in some regions, covering parts of a vast area from Washington in the east to Illinois in the Midwest to Georgia in the south.
Melody Merin, a 46-year-old Washington resident, also remembers the winged bugs鈥� last invasion, in 2004.
鈥淭hey were just flying everywhere,鈥� said Merin, who works in communications.
They were hard to escape, she said. When driving, 鈥渢hey鈥檇 be hitting your windshield. You couldn鈥檛 really drive with the windows open.鈥�
What else should people be bracing for during the few long weeks of the cicada visitation? The large insects getting caught in your hair, some residents recall鈥� The crunching sound made when you walk on countless cicada cadavers鈥�
And then there is the deafening racket, as Peter Peart clearly recalls.
鈥淚t鈥檚 a cacophony,鈥� said the 66-year-old retiree, who lives in Washington鈥檚 Columbia Heights neighborhood, where he witnessed the cicada invasions of both 1987 and 2004.
鈥淚t is loud, and it is nonstop. It鈥檚 incessant.鈥�
But it鈥檚 not the end of the world, he adds.
鈥淵ou get used to it,鈥� he said. 鈥淚t鈥檚 a background noise.鈥�
He admits to being amused by the whole 鈥渁mazing鈥� phenomenon, and is eager to see the expressions on the faces of people who have never been through a cicada invasion.
鈥淚 look forward to that,鈥� he said. 鈥淚 look forward to people鈥檚 reactions.鈥�
Overwhelming the predators
鈥淚t鈥檚 really quite unique,鈥� said John Cooley, an assistant professor of ecology and evolutionary biology at the University of Connecticut in Hartford.
The cicadas, which do no real damage other than perhaps to people鈥檚 nerves and eardrums, 鈥渏ust have a 17-year life cycle.鈥�
That life cycle 鈥� both long and yet mostly out of sight 鈥� sticks to a strict routine, he says.
鈥淥nce the soil reaches a certain temperature, about 62 Fahrenheit (17 degrees centigrade) on an evening that may be a little bit damp but not excessively rainy, nymphs will start coming out of the ground and then molt to adulthood.
鈥淭hen they鈥檒l hang around in the vegetation not doing much for about a week, and then they鈥檒l start doing鈥� what Cooley coyly calls 鈥渢he adult behaviors.鈥�
Which, translated, means a gigantic orgy repeated billions of times across the region.
For 鈥渢his is what this is all about,鈥� he adds: reproduction.
鈥淭hat noise that you鈥檒l hear is the male 鈥� only the males 鈥� making calls to attract female responses.
鈥淎nd then once a male and female are paired up, they mate, the female lay their eggs, then they die鈥� shortly thereafter.
The eggs, laid in tree trunks or branches, hatch six to eight weeks later. Ant-like juveniles then drop to the ground, where they burrow in for 17 years, drawing sustenance from sap in tree roots, before the unique cycle starts again.
The generally recognized estimate is that there will be 鈥渂illions and even maybe trillions鈥� of cicadas this spring, Cooley says.
By emerging in huge numbers, and with many years separating each appearance, they are able to overwhelm predators.
It is an effective survival strategy. For if squirrels, birds, raccoons and dogs enjoy feasting on the crunchy bugs for days, countless more cicadas will survive.
Meanwhile, residents of the US capital are trying to be philosophical about the fact that the insect invasion is set to coincide with the return of beautiful spring weather 鈥� something people have awaited with particular impatience after a year stuck mostly indoors due to pandemic-related restrictions.
Going for a stroll or heading to a park for a picnic might not seem so appetizing in the middle of a swarm of raucously chirping bugs.
鈥淚t鈥檚 a little cruel,鈥� Melody Merin said with a laugh.
鈥淚t鈥檚 a little bit like somebody who has a very twisted sense of humor.鈥�
