Smoky Mountain Synchronous Firefly Event 2020

Firefly Events in the Smokies

Smoky Mountain synchronous fireflies should not be missed!

Smoky Mountain Synchronous Firefly Event 2020. It’s never to early to start making plans to see the Synchronous Fireflies (and the Blue Ghost Fireflies) that will light up the night sky in late May and early June 2020 in the Great Smoky Mountains. Firefly viewing in the Smokies has become such a popular event that there are now several venues available to enjoy the spectacular shows.

The Synchronous Firefly (Photinus carolinus) and the Blue Ghost Firefly (Phausis reticulata) are two species that are found only in the Southern Appalachian Mountains which include the Great Smokies. And during the short mating season in late May and early June, both firefly species put on quite a show to behold! The male Synchronous Firefliesflash their little green-yellow bioluminescent lanterns in unison for about 6-8 blinks and then they go dark for a few seconds creating a sublime wave of light throughout the forest. The male Blue Ghost Fireflies don’t flash their blue-white lanterns, instead they glow continuously just a few inches above the ground. The ethereal experience of either nighttime show should be on everyone’s bucket list!  National Park scientists mostly use air and soil temperatures to predict the timing of each year’s mating season.

Synchronous Fireflies with Great Smoky Mountains National Park, TN
One of the most popular places to view the Synchronous Fireflies is in Elkmont in the Great Smoky Mountains National Park. This event has become so popular that a free lottery system was instituted for parking passes for the eight-day shuttle period to Elkmont. During this time of peak viewing, Elkmont is closed at nighttime with the exception of shuttle users and campers in Elkmont Campground. Dates for the 2020 Lottery and Elkmont Shuttle will be announced sometime in April 2020. HeySmokies will keep you updated, so be sure to check back with us. We’ll provide you all the details of what you need to know to register for the lottery. For more information in the meantime, visit Recreation.gov.

Blue Ghost Fireflies in DuPont State Recreational Forest near Asheville, NC
DuPont State Forest is located in Cedar Mountain, NC about 30 miles outside of Asheville. Due to the popularity of this location in recent years, some of the trails in the High Falls parking area will be closed during peak viewing season. Because the female Blue Ghosts stay on the ground, many have been killed by visitors wandering off of the designated trails. For more information, visit DuPont State Forest.

Fireflies on the Blue Ridge Parkway
Overlooks along the Blue Ridge Parkway are a great place to view starry nights as well as the fireflies in June! Usually the Blue Ridge Parkway Visitor Center in Asheville offers a family-friendly firefly viewing event. For more information, visit Blue Ridge Parkway Visitor Center.

Grandfather Mountain

It’s glow time as the discovery of Synchronous fireflies light up Grandfather Mountain. grandfather mountain is in Linville, North Carolina.

Grandfather Mountain’s staff and experts expressed glowing enthusiasm for the recent discovery of Photinus carolinus, the only species of firefly in North America whose individuals can synchronize their lighting display (or flash in unison).

It was a serendipitous discovery on Grandfather Mountain. Dr. Claude Sorenson, an entomologist from North Carolina State University, was hosting a workshop on the mountain and spending the night in the park’s guest cottage near the Woods Walk when he decided to find out what type fireflies might call this high altitude home. When he saw a few fireflies about 9:30 p.m. Sorenson knew these were no ordinary ones. “As it got dark, the numbers steadily went up and between 10 and 10:30 p.m., there were several hundred all around the guest cottage and Woods Walk, flashing synchronously,” Sorenson was quoted as saying. He confirmed his findings with East Tennessee naturalist Lyn Faust, an expert on the subject who has written a field guide on fireflies. Sorenson referred to Faust as “one of the best resources for anyone who is interested in learning more about these critters.”

Synchronous behavior is rare in fireflies. According to Sorenson, there are only a handful of this particular species around the world that do this, and for a long time, the amazing spectacle of large numbers synchronizing has been associated with a few geographical areas that range from New York to Georgia.

Sorenson’s recent discovery was at 4,200 feet compared to the fireflies in Elkmont, GSMNP at 2,200 feet.  Grandfather’s elevation range begins at 3,000 feet and peaks at nearly 6,000 feet. At the top, where temperatures are colder, the fireflies flashed in slower cadence, reported Amy Renfranz, Grandfather Mountains’ director of education, speaking of survey observations near the park’s Mile High Swinging Bridge. During one survey, Franz noted more than 1,000 fireflies from one overlook.

Smoky Mountain Synchronous Fireflies

Smoky Mountain synchronous fireflies are amazing!

As a general rule, fireflies, at most locations, are active for about two to three weeks. Due to the great elevation span of Grandfather, the display could last longer, Franz said. The show could start at the bottom of the mountain in early June and continue well into July at increased elevations, providing a bonus for the scientific community as well as spectators.

Jesse Pope, president and executive director of the Grandfather Mountain Stewardship Foundation, a non-profit organization that owns and operates the park, was excited about the news and said the discovery goes hand-in-hand with Grandfather Mountain’s mission to inspire conservation of the natural world by helping guests explore, understand and value the wonders of Grandfather.  “That’s something that makes Grandfather Mountain so special, that a visitor could do the discovering,” Pope was quoted as saying.

The park staff is already preparing for next year’s light show, brought to you compliments of Mother Nature.

For more information on the fireflies or other interesting events on Grandfather Mountain, call 800-468-7325, or visit www.grandfather.com

Both firefly species are common in other areas of Southern Appalachia and just perhaps during the month of June, you stay outside until around 10:00 p.m. when it’s good and dark and you sit quietly, you may be surprised at the light show in your very own backyard!
