Fireflies through Sam's eyes

Now that summer is over, the fireflies have pretty much ended their luminous show for the year.  Two years ago, you may have read a post about the fireflies of the Edge.  We are now up to 21 species, thanks to our friend and firefly leader, Lynn Faust, and her book  Fireflies, Glow-worms, and Lightning Bugs.  Many hours were spent this summer searching the preserve for new species, and new locations of rare species.

A photographer friend, Sam James, has been becoming more and more intrigued by these beetles. He spent some time observing the different species with us around the preserve. So I asked him if he could take photographs of the firefly shows we showed him.  Oh boy, did he. I had no idea his product would be so incredible.

Firefly displays are pretty much something you have to enjoy in person.  Even though they communicate with butts that illuminate, they are very hard to photograph and/or video to capture the actual experience.  But I think Sam has done an amazing job capturing their displays.  He was gracious enough to share his photos with us, which we would like to share with you.  Here are some of the firefly shows around the preserve.
One of the first fireflies to fill the fields of the Edge are Photuris quadrifulgens, the spring 4-flashers, which you can tell by this picture. 
More spring 4-flashers over a field in May along with a deer enjoying the show.

This scene shows the different patterns the spring 4-flashers can make.  Some flicker, some flash 4 times and some do a long glow.

Later in May, Another firefly with quick, single flashes fills the fields and surrounding trees.  These are Photuris tremulans, or the Christmas lights. This picture really shows why they are called Christmas lights!

Here, Sam caught a single Photuris quadrifulgens flying across a pond.

Photuris fireflies flash in the background while The Big Dippers, Photinus pyralis float upwards out of the field.

Some species are more secretive, flashing less often and hidden in the forest like these Photinus marginellus curtatus, or the little grays.

By mid-June, the newly discovered Photinus carolinus,  commonly called synchronous fireflies come out.  
By late night, a few preserve locations display hundreds if not thousands of these synchronous fireflies.
The synchronous fireflies flash together hence the name.  Here, Sam leaves the eye of the camera open exposing how many beetles flash in twenty minutes.

Photuris species showing their long glow with a unique perspective with the stars.  Looks like shooting stars!
More slow glowing Photuris looking like shooting stars.
We may never get to see the Aurora Borealis in southern Ohio, but shows like these might be the next best thing.

By late June and early July, the fields around the preserve become electric with a species called Photuris hebes, the Heebie- Jeebies.  Their single flashes occur every second and thousands of them blanket the field and shrubs
Late June and July starts the Big Scaries, Photuris lucicrescens.  They flash like a light bulb, or do a long slow glow lasting up to 3 seconds.
More Photuris sp. doing the "Chinese lantern" or slow glowing that produces a hypnotizing show.

Thanks to Sam James for taking the time to get out at night and use his expertise to capture and share the wonders that are fireflies in the eastern United States.  Not every part of the world gets to enjoy the bioluminescent beetles that most of us grew up with.  But through photos like these, people can get an idea of the immense communication show that is going on not far from our own backyards.  Sam's picture are wonderful and can't be beat....except for witnessing the beetles in person!
