Come this May, East Tennessee residents are in for a heavy dose of nature's own symphony — or cacophony, depending on whom you ask. After 13 silent years underground, Brood XIX cicadas are slated to swarm parts of Tennessee, bringing their deafening mating calls to the surface, as WBIR reported. Not to be out-done, Brood XIII will also burst forth in a rare double emergence seen across the Midwest and Southeast.

For the record, Memphis might just dodge the proverbial bullet; the University of Connecticut predicts that both the 13 and 17-year cicada broods will bypass the Mid-South. According to Local Memphis, those really looking to immerse themselves in this rare event will have to trek to Central Illinois, where, according to Mississippi State University's entomology specialist Blake Layton, it's an “unusual event that only happens for another 221 years.”

The cicada phenomenon is not just about the unbelievable noise which could reach up to 120 decibels but also the potentially visible impact on local flora. As the masses of cicadas emerge to mate, they could leave an increase in dead branches on trees, which, as Local Memphis states, can cause limited damage to decorative flora or orchards. However, these are but temporary afflictions and can be mitigated by netting vulnerable trees.

For those in Tennessee gearing up for the emergence of Brood XIX, the bugs' arrival is a guarantee, according to The Commercial Appeal. Yet, Memphis will breathe easy, as Brood XIII's emergence is confined to a small part of the Midwest; sparing the rest of the State, and granting those with entomophobia in the area, a much-needed respite. With this summer set to be a banner year for cicadas, you can expect picnics punctuated by the buzz of cicada serenades, and maybe, just maybe, the odd rescheduled outdoor wedding.
