2 broods of cicadas to emerge in Michigan at the once for the first time since 1803

For the first time in 221 years, two broods of cicadas will soon emerge to invade backyards in 17 states, including here in Michigan. Some are even referring to the upcoming spring and summer invasion as "cicada-pocalypse." In just a few weeks, the broods of cicadas that emerge every 13 years and the brood that emerges every 17 years will come up from the ground at the same time.
