The Synchronous Fireflies of the Great Smoky Mountains
Each year, usually in late May or early June, the synchronous fireflies of the Great Smoky Mountains light up in unison. You would not believe your eyes when you find out the reason.

Scientists found that male synchronous fireflies flash in unison to help females identify their species, as other predatory fireflies also flash at night. The Photinus carolinus flash pattern consists of 5-8 flashes, followed by an 8-second pause, repeating in sync. As more males join, entire forest sections pulse with light.
