Science Note- Cicadas Meet Citizen Science

Air Date: Week of

Seventeen-year cicadas are coming to the end of their season, and a team at North Carolina State University wants citizens to send them cicada corpses. Measuring the dead insects can help show how urbanization is impacting the species. Erin Weeks reports on the citizen science project.

CURWOOD: It's Living On Earth, I'm Steve Curwood. Just ahead, a race to discover some of the tiniest animals. But first, this note on emerging science from Erin Weeks.

WEEKS: They’ve got blood red eyes, translucent, orange-veined wings, and they’re in frenzied pursuit of mates. Seventeen-year cicadas are buzzing up and down the east coast, and as their season comes to a close, they leave behind billions of large, smelly corpses.

A team of scientists at North Carolina State University is taking advantage of their deaths to test a theory - and they want help. They’ve asked folks in cicada hotspots to collect the dead insects and mail them to their lab in Raleigh.

You see, there’s a lot you can learn about cicadas by measuring the asymmetry, or crookedness, of their bodies. In 1996, still in nymph form, this year’s brood of cicadas burrowed underground beneath trees to begin the long transformation into adulthood.

In the seventeen years since then, some forests have been replaced by roads and buildings, trapping many nymphs in the earth. Others faced stresses such as pollution and extreme temperatures. These conditions can interrupt normal insect development - and cause bugs to grow a little bit off-kilter.

To gauge just how much urbanization impacts cicadas, the NCSU team wants to measure these lopsided quirks in wing, vein, and leg sizes and compare specimens from rural, suburban, and urban locations.

So, if you live in the cicada zone, you too can contribute a few bodies in the name of citizen science. Happy hunting!

That’s this week’s note on emerging science. I’m Erin Weeks.

CURWOOD: There's more about the cicada project at our website, LOE.org.
