Blue Ghost Fireflies

Asheville's Blue Ghost Fireflies: Where and When to See Them

Article last updated 12/18/2025

If you’re in the Asheville area in late spring, you’re in for a breathtaking natural phenomenon—the blue ghost fireflies. 

These elusive fireflies emit a continuous blue-white glow rather than the typical blinking pattern seen in other fireflies. Unlike their flashing relatives, blue ghost fireflies create an eerie, floating effect, making the forest feel almost enchanted.

Unlike other fireflies, blue ghosts have a distinctive blue-green glow that can last up to a full minute. Males float low over the forest floor with a steady glow, while females—who do not fly—emit a fainter light from the ground. Their mating season is shorter than other fireflies, lasting only a few weeks each year. Conservation efforts, such as limiting artificial light and preserving their natural habitat, are crucial to protecting these rare creatures.

What are the best times and conditions for seeing Blue Ghost Fireflies?

The peak season for blue ghost fireflies is from mid-May to early June. They thrive in warm, humid conditions, usually appearing just after sunset. For the best experience:

  • Choose a night with little to no moonlight for maximum visibility.
  • Be patient—let your eyes adjust to the darkness.
  • Avoid using flashlights or phone screens, as artificial light can disrupt the display (use red lights if necessary).
