Trillions of Brood X cicadas emerging for first time in 17 years: What to know CNET 2 hrs ago Leslie Katz © Provided by CNET Periodical cicadas emerge from underground in the spring of their 13th or 17th year. Fifteen US states, and Washington, DC, are about to see a whole lot of them. Getty Images Parts of the eastern United States are about to witness a remarkable natural spectacle: trillions of cicadas tunneling out from their subterranean homes for the first time in 17 years for an inescapable mating frenzy.    Periodical cicadas, as they re known, are different than annual cicadas. They spend almost their whole lives a foot or two underground, living on sap from tree roots.

Three whales wash up dead near San Francisco, 8 in 5 weeks

The whales spend the winter off Mexico’s waters, then they head back north and stay off the coast of California in spring and summer.

Although the gray whales are still migrating north from Baja California, fewer whales have stranded this year than in the two previous years just 68 so far. While the death of these whales is tragic, Milstein said, it offers an opportunity to “better understand what’s affecting the other 20,000 remaining gray whales out there.”

The investigation is continuing. Although the number of dead whales may seem alarming, the numbers are actually lower than they have been the last two years, said Michael Milstein, an NOAA spokesman.
