This spring, residents of western North Carolina are witnessing a remarkable natural event: the emergence of Brood XIV, one of the largest broods of 17-year periodical cicadas. These cicadas are the offspring of cicadas that emerged in 2008 -- when George W. Bush was president, the first film in the Marvel Cinematic Universe ("Iron Man") was released , and The Motorola RAZR was the top-selling phone. 

Triggered by warming soils, Brood XIV is now surfacing in Buncombe, Burke, Caldwell, Catawba, Henderson, McDowell, Mitchell, and Wilkes Counties. 

Periodical cicadas (Magicicada spp.) are unique to the eastern United States.Unlike annual cicadas, which appear every summer, periodical cicadas spend 13 or 17 years (depending on the species) underground as nymphs, feeding on tree roots.After spending most of their life underground, they emerge en masse to molt, mate, and lay eggs before dying within a few weeks.

They'll be hard to miss -- if not by sight, then by sound! Male cicadas produce a loud buzz which can reach over 100 decibels. While noisy to us, this is very attractive to female cicadas, which have one goal in their aboveground life: to reproduce. 

Fear not! Cicadas do not bite or sting and are harmless to us and our pets. However, their egg laying, which entails cutting into twigs and stems with a saw-like egg-laying structure, can harm plants. Usually, this doesn't cause long-term damage, but branch tips may be killed. Anecdotally, reports suggest this damage results in a flush of new growth the following growing season.

So, enjoy the short-lived cacophony! This particular show won't be back for another 17 years, in 2042!
