This could be a noisy summer for southeastern and western Missouri. A brood of 17-year periodical cicadas will emerge in northwestern Missouri, and a brood of 13-year periodical cicadas will surface in southeastern Missouri. Wingless nymphs will come out of the ground, climb up on an object like trees, sheds, and homes. Then they break out of their exoskeleton and emerge as winged adults. Bruce Barrett, entomologist for University of Missouri Extension, says the males will take to the trees and sing, sing, sing.
That noise is a come-hither call to females. The periodical cicadas have only one purpose, to mate and reproduce. Barrett says this amazing event, which only occurs in North America won’t last long.
Then the less colorful, annual, or dog day cicadas will begin their song later in the summer.
