Periodical cicada Brood X will emerge in 15 states in 2021
Magicicada periodical cicadas often emerge one or four years earlier or later than their main brood is expected to emerge. When they do, we call them precursors or stragglers (the most common name in scientific literature). This behavior is natural and expected, and how Magicicada have branched off into new broods…
