Where billions of cicadas will emerge this spring & the next decade

For 17 years, cicadas do very little. They hang out in the ground, sucking sugar out of tree roots. Then, after this absurdly long hibernation, they emerge from the ground, sprout wings, make a ton of noise, have sex, and die within a few weeks. Their orphan progeny will then return to the ground and will live the next 17 years in silence.

Over the next several weeks, billions of mid-Atlantic cicadas will hear the call of spring and emerge from their cozy bunkers. This year's group is known as Brood V, and they were born in 1999 during the spring the first Star Wars prequel bewildered moviegoers.

But while they will emerge in biblical numbers, they'll be blanketing only a small slice of the country.

Cicadas appear every year on the East Coast, though every year it's a different 17-year crew that wakes up (Note: There are some 13-year broods of cicadas in the Southeast, too.) Emerging in these humongous yearly batches is likely an evolutionary strategy. There are so many cicadas, all at once, that predators can't make a meaningful dent in their numbers.

In sum, the broods lay claim to much of the eastern United States, stretching from New England to Oklahoma. You can see all the United States broods on this U.S. Forest Service map below.

This year, it's Brood V's turn . The brood mainly lives in Ohio and West Virginia, with some members spilling over to Pennsylvania, Maryland, and Virginia.

Here's a closer look at where Brood V lives, according to the Forest Service. Note that the brood hasn't taken up residence in the major metropolitan areas of Pittsburgh, Cincinnati, or Washington, DC. Cleveland, however, is likely to see some.

After lying beneath the earth for up to 17 years, cicadas venture above ground as a massive group to shed their larvae shells, sprout wings and sing for a mate.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

The Appalachian Mountains, the Scottish Highlands, and the Atlas Mounts in Africa were the same mountain range

The Central Pangean Mountains was a prominent mountain ridge in the central part of the supercontinent Pangaea that extends across the continent from northeast to southwest through the Carboniferous , Permian Triassic periods. The mountains were formed due to a collision within the supercontinents Gondwana and Laurussia during the creation of Pangaea. It was comparable to the present Himalayas at its highest peak during the start of the Permian period. It isn’t easy to assume now that once upon a time that the Scottish Highlands, The Appalachian Mountains, the Ouachita Mountain Range, and the Atlas Mountains in northwestern Africa are the same mountains , once connected as the Central Pangean Mountains.

Human Emotions Visualized

Despite significant diversity in the culture around the globe, humanity's DNA is 99.9 percent alike. There are some characteristics more primary and typical to the human experience than our emotions. Of course, the large spectrum of emotions we can feel can be challenging to verbalize. That's where this splendid visualization by the Junto Institute comes in. This visualization is the newest in an ongoing attempt to categorize the full range of emotions logically. Our knowledge has come a long route since William James suggested 4 primary emotions: fear, grief, love, and rage. These kernel emotions yet form much of the basis for current frameworks. The Junto Institute's visualization above classifies 6 basic emotions: fear, anger, sadness, surprise, joy, love More nuanced descriptions begin from these 6 primary emotions, such as jealousy as a subset of anger and awe-struck as a subset of surprise. As a result, there are 102 second-and third-order emotions placed on this emo
