“After hanging around underground for 17 years, billions of flying bugs known as cicadas are due to sweep over the East Coast starting sometime in the next month. And although it’s too early to predict exactly where or when the brood will appear, this spring’s emergence should rate as the most closely watched bug-out in history.
“For entomophobes, this is the season of despair. For the entomophiles, this is the season of joy,” said University of Maryland entomologist Michael Raupp, using highfalutin terms for bug-haters and bug-lovers.
The outbreak is expected to start in the Carolinas in April or early May, and work its way up northward to Washington, Philadelphia and New York by early June. Some observers have already reported the first signs of the emergence. The timing depends on the weather: Cicadas dig “escape chimneys” up from the ground where they’ve been maturing for the past 17 years — and when the temperature reaches 64 degrees Fahrenheit (18 degrees Celsius), that signals the insects to rise up, wriggle out of their shells, take wing and look for mates.
“Be ready for the buzz
The bugs are mostly harmless to plants and humans. The worst a cicada can do is poke you with its pointy proboscis. But the 90-decibel buzz of a sky-darkening swarm can be a bit unnerving to the unprepared. Raupp recalls one harrowing tale from 1962’s outbreak, when “the kids were shrieking in the playgrounds as cicadas divebombed them.”
In Raupp’s view, however, the pluses far outweigh the minuses. The cicada nymphs help aerate garden soil with their burrowing, and when they emerge, the bugs represent a culinary bonanza for birds and other species. (They’re said to taste like asparagus. Or shrimp.)
Besides, cicadas are cool. “Without a doubt, they are a true marvel of nature and one that should be enjoyed whenever possible,” Raupp writes on his Bug of the Week blog.”

When I lived in DC in 2003, there was a cicadia-mania, however it wasn’t as bad as people expected. #1 reason is development. If there has been a lot of new construction in the last 17-years, the lavae are gone. period. In a less developed rural area, it can get quite loud. Dense urban areas, not so much.

I agree with Donna . the cicadas ( cigales) are one of the treasures of Provence and the Riviera . you even can buy jewelry featuring them .
