Billions of cicadas are expected to buzz across the Show-Me State this month

Billions of cicadas are expected to buzz across the Show-Me State this month as two broods emerge at the same time. These broods last emerged together in 1803 and will not appear together again for another 221 years, according to MU Extension. Specialist Tamra Reall says your grandchildren’s great-great-great grandchildren likely will be the next group to experience the dual emergence of the cicada broods that appear in 13- and 17-year life cycles. The synchronized male noise can be louder than a jet engine. Cicadas are drawn to the vibrating sounds of power tools and lawnmowers.
