After 17 years of hiding, large swarm of Brood X cicadas expected to emerge

Starting next week, trillions of Brood X cicadas will begin their assault on nearly all of the country, east of the Mississippi River. They've been lying in wait for 17 years until the time and temperature is right to begin their deafening descent upon millions of Americans. Meteorologist and CBS News climate specialist Jeff Berardelli reports.

Each weekday morning, "CBS This Morning" co-hosts Gayle King, Anthony Mason and Tony Dokoupil deliver two hours of original reporting, breaking news and top-level newsmaker interviews in an engaging and informative format that challenges the norm in network morning news programs.
