Watch this time lapse of a Brood X cicada molting | #短裤

Wait for it. Billions of Brood X cicada nymphs are emerging from the ground in 15 states — a natural phenomenon that only occurs every 17 年. After feeding off tree roots for nearly two decades, the nymphs crawl out of the soil and climb trees and other vertical structures in search of a suitable place to shed their shells. Molting takes several hours. After it has emerged from its carapace, the cicada must wait several more hours for its body and wings to harden. In this time-lapse footage captured by entomologist Michael Raupp of the University of Maryland, one such Brood X cicada makes its transformation into adulthood. It, and billions of other successful molters, will have four weeks to mate before dying — if they don’t become food for predators first. #短裤
