Fireflies definitely bring out the kid in us. And you'll find some rare species in the Blue Ridge and Great Smoky Mountains, but they only come out for a short visit! Fireflies (also called lightning bugs) are beetles. They take one to two years to mature from larvae, but will live as adults for only about 21 days. While in the larval stage, the insects feed on snails and smaller insects. Once they transform into their adult form, they do not eat. Their light patterns are part of their romantic mating display.
Synchronous Firefly Tours in NC
On the North Carolina side of the Smoky Mountains, you can take a Synchronous Firefly Night Walk with Cataloochee Valley Tours in Waynesville on June 1-18, 2017 (dates may change a little depending on when fireflies appear this year). You'll be outfitted with a safety vest and flashlight for your walk in the dark of night to their secret viewing locations in small groups. Tours last from 8:30 PM until 11:30 PM (weather permitting) and costs $80/person. Go to the Cataloochee Tours website for reservations.
Synchronous Fireflies in the Great Smoky Mountains: Lottery
2017 Dates TBA (2016 dates were May 31-June 7) Synchronous fireflies (Photinus carolinus) are one of at least 19 species of fireflies that live in Great Smoky Mountains National Park. They are the only species in America whose individuals can synchronize their flashing light patterns. The Great Smoky Mountains is one of the few places in the world to see the synchronous fireflies, and people flock here from all over the country to see them for a couple of weeks in late May or early June. The season varies a little depending on weather conditions. Crowds gather at Elkmont to view. You can either camp there or take a shuttle from the Sugarlands Visitor Center in Gatlinburg (read more below).
Parking passes for shuttle transportation to view the synchronous fireflies at Elkmont will be distributed via a lottery system (sign up in late April). Since 2006, access to the Elkmont area has been limited to shuttle-service from Sugarlands Visitor Center in Gatlinburg during eight days of predicted peak activity to reduce traffic congestion and provide a safe viewing experience that minimizes disturbance to these unique fireflies during their two-week mating period. Watch for lottery dates in 2017!

Joyce Kilmer Memorial Forest
Another recently discovered spot to watch synchronized fireflies is deep in the Nantahala National Forest at Joyce Kilmer Memorial Forest in Graham County. They typically appear between late May and mid-June. Watch them from dusk until about 11 PM. If the moon is bright, the show will be delayed 30 minutes or so. On cool nights (below 50 degrees) and on misty evenings following rain, the flashing may be greatly reduced or altogether absent. Arrive before sunset and bring a flashlight covered with blue or red cellophane in order to retain your night vision. Walk up the trail to a bench and watch the woods light up. You can also watch the blue ghost fireflies here in June. Read more about Joyce Kilmer Forest.
Blue Ghost Fireflies
For just a couple of weeks a year, the enchanting blue ghost fireflies "Phausis reticulate" make their appearance in several valley areas near Asheville. They are different from other fireflies since their light stays on constantly and they fly just above the forest floor. It's a romantic story! According to Brevard College Professor Dr. Jennifer Frick-Ruppert, "the males are small with black elytra and brownish wings, about 1/4 inch in length and delicate. Females are flightless and grublike. They do not flash. Instead, they glow constantly with a dim bluish white light, drifting silently just inches off the ground. With hundreds or thousands of these fireflies meandering aglow over the dark forest floor, the ground itself seems eerily adrift."
Due to overwhelming crowds, DuPont State Recreational Forest will close several trails in the High Falls parking area from mid May through early June 2017 during the annual appearance of the Blue Ghosts. Since Blue Ghosts love moist, lush forest floors and females stay on the ground, they are easily killed by visitors wondering off the trail. And lights from cell phones or flashlights can interupt with their mating communication.
