Photinus carolinus is a species of rover firefly whose mating displays of synchronous flashing have fascinated both scientists and tourists. As individual females synchronize with males nearby, waves of alternating bright light and darkness seem to travel across the landscape. Firefly displays typically occur in early June near Elkmont, Tennessee, in the Great Smoky Mountains National Park, near Gatlinburg.

Increasing numbers of people come each year to a trailhead near Elkmont to see them. Scientists use a degree day model to try to predict the onset of each year's peak display.

Driving and parking near Great Smoky Mountains National Park are strictly regulated during the two-week P. carolinus mating season. Would-be visitors are required to park at the Sugarlands Visitor Center and wait for a trolley to take them to the viewing site.
On weekends there may be a four-hour wait for transportation.
