Grandfather Mountain is one of the best places in the Appalachian Mountains to see rare and endanger animals. One of those species of is a species of firefly, known as Photinus carolinus. What makes this firefly so special?
The Photinus carolinus is the only species of firefly in North America whose individuals can synchronize their lighting display, meaning they can flash in unison. Photinus carolinus famously resides in the Great Smoky Mountains National Park, where it is a major draw for visitors from late May through early June.
Every summer, Grandfather Mountain hosts a Grandfather Glows nighttime viewing event which take place on the lower half of mountain to view this spectacular phenomenon of millions of fireflies glowing at once.
This year it takes place from June 26, June 29, July 1. 7-11 PM. You can sign up for the waitlist here https://grandfather.com/waitlist/
