Every morning, we wake up to discover hundreds of empty nymphal cicada cases and adult cicadas just chillin’, waiting for their exoskeleton and wings to harden. After a few hours, they start flying up, up, up into the high trees. Soon, they will work together to create a wall of sound, find mates, lay eggs and die. Their offspring will fall from the trees, burrow into the ground and feed for another 17 years. I will again be there to witness their emergence – next time with a better camera.
Editor’s notes:
Marianne Alleyne is interested in how biological systems can lead to innovative design in human society. The Alleyne Bioinspiration Col-lab-orative studies the surface features of the wings of various cicada species, including those in Brood X, because they have superhydrophobic and antimicrobial functionalities.

When The Brood X Cicadas Descend In Masses, So Do Bug Scientists
Millions upon millions of Brood X cicadas are emerging, and entomologist Marianne Alleyne didn t want to miss it. I didn t see it 17 years ago, and I wanted to experience it, says Alleyne. My brother-in-law actually put it perfectly: This is your entomology Woodstock, isn t it?
Brood X isn t the only group of cicadas that spends nearly two decades underground, but it is the biggest and most famous. The return of these enormous black bugs only lasts about six weeks and is a rare chance for researchers to try to understand everything from the creature s basic biological design to the impact of its mass appearance on other living creatures.
