Fireflies at Blue Spring
Did you know Blue Spring has a firefly season?
From roughly mid-March through mid-April, the firefly species known as the Florida single snappy (Photuris congener) begins a brilliant light display under the forest canopy.
To learn more about this species, you can attend our Firefly Nights Fundraiser that takes place each spring. You’ll be able to listen to an educational Firefly Chat and then walk the boardwalk trail after sunset to look for fireflies.
Become a member to get early access to Firefly Nights passes when they become available!
There are currently multiple different membership levels to choose from.
There’s always a chance you’ll see a small handful of fireflies at our other nighttime events throughout the year. Check out our upcoming events page, and get a pass for our next Full Moon Hike or Park After Dark event.
Coffman’s Glow Scale
Ronnie Coffman has been a volunteer at Blue Spring State Park for 20 years. Thirteen years ago, he began his fascination with Blue Spring’s fireflies, and for over a decade he has been educating visitors on how to observe and respect them. Each night, the firefly activity is measured using the Coffman Scale, and we share the rating the following morning on @bluespringstatepark_ on Facebook and Instagram.
The Coffman Scale reflects the stage of the season, not the quality of the experience. Firefly season naturally begins with lighter activity, gradually builds to a peak, and then tapers off again. Early‑season and late‑season nights often fall in the 1–2 range, while peak nights reach a 5.
No matter the number, every firefly night is magical, and each stage of the season offers its own unique beauty.
