The Two-Sided Story of Periodical Cicadas

Forestcast

Any day now, periodical cicadas will emerge across 15 states stretching from Illinois to New York and northern Georgia.

Two scientists, one who’s tracked the aboveground movements of these cicadas, and another who’s unearthed the belowground impact of these insects, take you inside the many mysteries and forgotten elements of these evolutionary enigmas.
