THE CICADAS ARE COMING!!!

there is no reason to fear these insects, which grow to about 1.5 inches in
length, with big red compound eyes. Cicadas don’t bite. And don’t worry about
your plants. They’ll be fine. There’s no need to reach for the bug spray.

17 Years to Hatch an Invasion
By CARL ZIMMER
From North Carolina to Connecticut, billions of creatures with eyes the color of blood and
bodies the color of coal are crawling out of the earth. Periodical cicadas are
emerging en masse, clambering into trees and singing a shivering chorus that
can be heard for miles.
makes this emergence truly remarkable, however, is how long it’s been in the
making. This month’s army of periodical cicadas was born in 1996. Their mothers
laid their eggs in the branches of trees, where they developed for a few weeks
before hatching and heading for the ground. “They just jumped out and rained
down out of the trees,” said Chris Simon, a cicada biologist at the University of Connecticut.
Clinton-era larvae then squirmed into the dirt and spent the next 17 years
sucking fluid from tree roots. Now, at last, they are ready to produce the next
generation. The adult males are snapping rigid plates on their abdomens to
produce their courtship song. The females are clicking their wings to signal
approval. They will mate and then die shortly afterward. Their time in the sun
is short, but their 17-year life span makes them the longest-lived insects
17 years, we humans are just barely getting started in life. A mouse, by
contrast, needs just seven weeks to become sexually mature, and it will live
only a few years more. Yet mice are like Methuselah compared with the
gastrotrich, a water-dwelling invertebrate the size of a poppy seed. Three days
after it hatches, it’s laying eggs, and days later it’s dead.
any given species, the pace of life evolves. Natural selection is constantly
shaping its genes, adapting it to its environment. How long a species lives and
how much of that life it takes to reach adulthood are evolving just like every

strategy has worked so well, in fact, that cicadas have lost their other
defenses. They even fly sluggishly. When errant cicadas emerge in the wrong
year, they are quickly eradicated by birds — along with their errant genes.
fast-growing cicada, Dr. Simon suspects, natural selection favors patience.
“It’s better to wait till everyone catches up,” said Dr. Simon. As a result,
evolution favors a long life in cicadas.
some of the periodical cicadas in the eastern United States are emerging at the
moment. They’re known collectively as Brood II. In other regions, other broods
emerge in different years. Last year, for example, Brood I emerged in Virginia, West Virginia and Tennessee. All told, there are 15 broods lurking in the ground
around the United States. Twelve have a 17-year cycle, and three have a 13-year
You knew this one was coming.
Earlier this month, we told you about a
U.N. report that makes the
case for insects to improve global food security: They're cheap, plentiful
and environmentally sustainable. Now, the coming of the 17-year
cicadas provides East Coast Americans, for whom bug eating is considered
novel at best, with an opportunity to try local insect cuisine.
If you're willing to try cicada
cookery, there's a book to guide your way, as NPR's Yuki Noguchi reports
Wednesday on All Things
published in 2004 and available for free
online, features recipes for cicada dumplings, tacos and chocolate-covered
Author Jenna Jadin tells Yuki that,
before cooking, you should break off the legs and wings — "they kind of
tear off pretty easily."
"Then rinse them off," Jadin
says, to "make sure all the soil bacteria is off of them."
Back when cicadas infested Chicago in 2007, freelance food writer David Hammond also gave the critters a culinary go.
"My goal was to get them right as they were coming out of the
ground," he tells NPR. "Young. Veal, if you will. Ha ha."
He realizes Western diners might be put
off or grossed out by the idea of eating bugs — but weird is all relative, he
notes. (After all, 2 billion people already eat bugs, mostly in Asia, Africa,
Latin America and Australia.)
"Cheese is the grossest thing in
the world," Hammond says. "You know, it's rotten milk. You eat rotten
milk? That's disgusting! Yeah, well, we love it."
Then there's the fact that — hate to
break it to you — you've probably already eaten bugs without realizing it.
"Insects are a part of all
processed foods," Jadin writes in her cookbook, "from bread to tomato
ketchup — it's impossible to keep mass-produced food 100% insect-free. There
are regulations stating the maximum amount of bug bits that food can contain
and still be fit for human consumption."
Sit back and digest that for a second.
But of course, the big question is: How
do they taste? Word on the street is that cicadas are kind of nutty or kind of
Jadin cooked up a batch of the noisy,
red-eyed bugs for our intrepid reporter to sample: candied with brown sugar and
seasoned with Sriracha, then baked in the oven at 350 degrees for 20 minutes.
"It's kind of like caramel
popcorn," Yuki tells us.

Serves 2 amply
1 cup freshly emerged
cicadas 2 quarts clean boiling water salt to taste
1. Gather cicadas from
tree trunks and shrubbery, just after they have come out of their nymphal
shells; they should still be soft and whitish, like soft-shelled crabs.
2. Drop the cicadas into
water after it has come to a full boil; water may be salted.
3. After 12 minutes,
drain and season to taste.
4. As a variation, try
older cicadas, 30 to 60 minutes after they emerge; they are still tasty, but
have hardened and darkened. They should have their wings and legs snipped off
5. For still another
variation, gather nymphs while they are still living underground or just after
6. Boil as above.
7. Use boiled nymphs in
much the same way you would use cooked shrimp. For example, stir-fry in a wok,
combining with favorite spices, vegetables and sauces.
