It’s firefly season at Blue Springs. Wait, what’s firefly season?

Blue Spring State Park,  home to manatees in the winter and a favorite place for a swim in clear, bracing spring water in the summer, will allow visitors to stay one hour after closing during firefly season from now through March 31.

Really? When I first read this, I thought it was an April Fool’s joke. As a South Florida resident, am I alone in my ignorance of “firefly season”? But I did a quick Google search, and, indeed, Central Florida is awash with fireflies at dusk near bodies of water in the late March and early April.

There is a firefly season and Blue Spring, located 35 miles north of Orlando in Orange City, is firefly central.

In 2019, “firefly season” began in mid March and will continue through Sunday, March 31.

To allow visitors to enjoy this phenomenon, Blue Spring lets visitors stay after the traditional closing time to see “Mother Nature’s light show.”

Here’s how it works:

You must must arrive before sundown to gain admission. Please bring a flashlight to safely navigate the paths and boardwalks after dark. Best viewing is along the boardwalk between the Thursby House and the Spring Boil. Insect repellent for mosquitoes may be needed.

One park staff member describes the scene as “pretty spectacular …..It’s like a bunch of Christmas lights thrown out there into the woods.”

    When I was a child, they were so thick it seemed a nightly occurrence. I remember watching them from my bedroom window until I would fall asleep. We would ride horses in the evening through swarms of them down in the orange groves. We would see who could trap the most in a jar. (yes, they were released alive and flashing).

    50+ years later, I wondered why I never see them anymore. I was digging around for an answer and found this article. Thank you.

    Never seen blue fireflies. Green or Yellow…but now I want to find these! This time last year I experienced a magical twinkling forest at Ft. Clinch. I am setting out next weekend to try to find this again, on the Georgia Golden Isles. Maybe too soon, since it’s further North. It was so beautiful, like a dream.

    Last night, my wife were taking our dog out side, and while she was out there, looked up to see the stars at 1 am in the morning. She was amazed to see the large maple tree in our back yard light up! She came in to get me up, and we both went back outside. For more than 35 minutes, the whole top of the tree was blue lightning bugs! It was amazing to see. I am 61 years old and have never see this before. Been in FL all my life. We live on Lake Orienta in Altamonte Springs. It was pretty cool last night. I wanted to tell someone, after looking online, we believe they were Blue Ghost lightning bugs. The tree was lit up bright blue!

        Yes!, I have seen blue fireflies. In our back yard last year in North Port,Fl. (Sarasota County). I thought I was seeing things! ~ the first few blue flashes really surprised me. There is a preserve behind our house so it’s dark out late at night.I watched from our screened in lanai. It was magical and hope I get to see it again.

          From what I was told about the fireflies at Blue Spring State Park, they were present for about three weeks. Not sure if that will be true for yours. But thanks you for sharing.
