One of the craziest life cycles of any creature on the planet’ culminates after 17 years underground.
Sifting through a shovel load of dirt in a suburban backyard, Michael Raupp and Paula Shrewsbury find their quarry: a cicada nymph.
And then another. And another. And four more.
In maybe a third of a square foot of dirt, the University of Maryland entomologists find at least seven cicadas — a rate just shy of a million per acre. A nearby yard yielded a rate closer to 1.5 million.
And there’s much more afoot. Trillions of the red-eyed black bugs are coming, scientists say.
