Cicada Data - "Have Eggs, Will Travel"

Credit: National Science Foundation

Audio Transcript:

And now a bit of Cicada Data...from the National Science Foundation.

Announcer: Like apples, cicada eggs don't fall far from the tree. When the eggs hatch, the young burrow into the soil, find themselves a root, and settle in for years of sap-sucking fun. But when they emerge, do they in turn lay their eggs in the same, but now older neighborhood? Biologist Keith Clay of Indiana University explored that question, under a National Science Foundation grant. He found cicadas emerged throughout the forested plots he studied...but not in open, scrubby, regenerating areas.

Clay: But when we looked at where cicadas were laying their eggs, a very different pattern emerged. Very little egg laying was taking place in the middle of these forests, and the majority of it was taking place in these young, scrubby, regrowing areas...

Announcer: ...suggesting that cicadas try to move to younger habitats each time they emerge. Have eggs, will travel.

For Cicada Data, I'm Emilie de Azavedo.
