![]() When they spot a pattern that they like, they flash the same signal back at the male as an invitation to come on over. Each waits for a specific pattern of blinking light – sequences are unique to each species. Meanwhile, female fireflies wait in the leaves, observing the males’ flashes. In firefly mating rituals, the males cruise by, flying around and flashing their signals to let the ladies know that they are l ooking for love. Park Rangers will be stationed at the intersection of Little River Road and the Elkmont Entrance Road to manage this restriction.Flashing together makes it easier for members of the species of Photinus carolinus fireflies to locate appropriate partners for mating, the study found. Starting at 5:30 p.m., the public will not be allowed to access the Elkmont Entrance Road, except for those camping at the Elkmont Campground. Dogs/pets are not allowed on the trolleys or on the trail. Visitors can bring lawn chairs, and carry food and water in backpacks, which can fit on their laps in the trolleys there are no services available. each night.Ĭoolers and alcoholic beverages are prohibited. The last trolley to return to the visitor center will be at 11 p.m. After 9 p.m., trolleys will only be taking visitors back from the Little River Trailhead to the visitor center. The last trolley to pick up visitors from the visitor center will be 9 p.m. Trolley service will be provided from the Sugar Lands Visitor Center bus/RV parking area on a first-come, first-served basis starting at 6 p.m. The Little River Trailhead parking area will be used to serve as a turn-around area for the trolleys. "No Parking" at the Little River Trailhead in Elkmont will be enforced. It is recommended visitors bring flashlights with red cellophane covers to reduce white light. People come from all over to see it, and some even plan their entire vacation around it. ![]() It is the only species of firefly in the United States that is able to synchronize its lights. The synchronous firefly species - Photinus Carolinus - is one of 14 that live in the Park. It’s an amazing event to watch, the synchronized light display visitors to the Great Smoky Mountains National Park are treated to for a couple weeks this time of year. The show is put on completely by thousands, possibly millions, of fireflies during their mating season. Once they’re all grown up, they only live for about 21 days, during which time they put on their show, and mate. The synchronous fireflies can take as many as two years to mature into adults from larvae. ![]() At first, the flashes are random, but they change to synchronized flashes that last six seconds, then go off for ten seconds before repeating. The synchronous fireflies start about 9:30 p-m. The insects begin their show later than most "lightning bugs," which light up at dusk. The synchronized display is actually a mating ritual in which the male attracts the female by flashing a yellow-green light twice per second, in timed bursts of four to eight flashes.ĭuring their two-week mating ritual, the synchronous fireflies at Elkmont flash in unison. The fireflies in the Smokies - unlike most fireflies - light up in unison. Elkmont is just outside of Gatlinburg past the Sugar Lands Visitors Center towards Townsend. Some call them fire flies, some call them lightning bugs but they're actually bioluminescent beetles, a species known to scientists as Photinus Carolinus, and one of their most spectacular light shows takes place each June at Elkmont in Great Smoky Mountains National Park.
