OT: Snychrononous fireflies

John K Jordan

The synchronous fireflies are at it again in the woods and even in the yard near the house. I've been watching them at the farm here and at our previous house for at least 25 years now. The first few nights I see them there are not many and they are not quite synchronized but in just a few days they are everywhere and synchronized nicely. They stay fairly low at first, about shoulder height or lower, but later tend to move higher in the trees. Their flash is a series of very short blinks unlike normal fireflies whose blink is slow enough to see a trail when they move.

It's fascinating to see 50 fireflies all blinking in perfect unison. Every once in a while a rogue flies in from another area out of sync but he quickly gets with the local program.

It's humorous to hear of people paying for a lottery ticket, paying driving hours, paying a big parking fee, then waiting for their turn to be shuttled to a viewing area in the Great Smoky Mountains. When I was working a woman told of her viewing adventure in the Smokys then got visibly upset when I told her I watch them in our woods every year. Not too many years ago insect scientists declared they were only found in first one, then two areas in the country. I wrote to some researchers and told them about ours but never heard back.

Once I collected a bunch with a net and put them in our screen-in porch. They didn't blink once!

I heard about the synchronicity several years ago, and pointed it out to a few of the locals – well I’m now the bug guy on the hill. I don’t mind (much) , but I’d rather have a different nickname. KING, for example.

I have an area of about five acres to view and I must say while the light show is fantastic, the area seems too large for the majority to link up as one. Close to the house, not at the same time, but a sort of signal and response at least until they meet. Cheap thrills!

I liken it to early mail cross country pilots searching for a beacon—nice to home into when you are lost.

Humm, I have to wonder how many more you would have without the guinea fowls?

I don't know much about this species, but I seem to recall something about it being mostly males trying to attract the lady beetles. Do the early instars spend most of their life cycle underground, or maybe high up in the tree-tops?

We don't live so far apart but I guess that mine don't have a proper sense of rhythm. They flash just fine but can't seem to get it together.

Do those you see have very short blinks like a strobe light or longer blinks, maybe 1/2 second or so? We have both kinds. The strobe light bugs are always around trees and the slow blinkers are more often in the fields. When the slow ones move you can see a short trail of light.

Just libertarian ones here

Bill Tindall, E.Tn.

While we have hundreds of them blinking over the pastures at night, and they blink in every frequency for Morse code to comets, I have not detected any coordination.

They hide in the grass by day and move higher into the trees as night progresses. They are larger than their Yankee cousins with correspondingly brighter flash. In the winter when it is not too cold we see the glow worm stage among the gravel in the driveway. Unclear why it is a good idea for a worm- like critter to announce to predators with a glow that dinner is crawling nearby.

Wait until they discover music

Bill Houghton, Sebastopol, CA

Afro-Cuban. Jazz. South African. The possibilities are endless.

You'd have to imagine the notes moving up and down, but watching different sections of your yard doing the point and counterpoint in one of Bach's fugues would be pretty nifty.

Even without that, wow. California is lacking in fireflies, alas; if we ever go through the Midwest in the summer, we'll hope we get to stay in a park with that species.

To be honest, I never really studied them enough to see the difference. To my uninformed eyes, "it is dark, the bugs are flashing" pretty much covers it. Next time I'll try to figure them out. I'm wondering if it just isn't dark enough here with the Knoxville/streetlight light pollution for them to act normally. Maybe I should be looking out the back of the house and up into my woods up the ridge instead of the front toward the road?

I'm in the country now but saw both types when we lived in Oak Ridge. However, we were on the edge of the greenbelt against 1/4 mile of nothing but woods.

Watched last night

Bill Tindall, E.Tn.

Made a fire and cooked a steak and baked potatoes on the edge of a clearing on some timber land we own. At dusk the fire flies began to emerge from the low grass (I had recently cut grass). For about 1/2 hour they would flash as they rose from the ground. Concentrated near the ground they made quite a light display.

Some groups of half dozen or so would flash together but not the whole flock. Curiously they would flash as they rose, then loop back toward the ground in stealth mode, only to rise and flash again. As it got darker most, but not all, rose to the tops of the trees.

Then a deer, upset at our intrusion, blew in annoyance. Later the Barred Owl got up and clocked in with its characteristic hoot. It was a nice night. It didn't rain, and there were no mosquitoes.

They are pretty thick in Indiana too, as a child I used to catch several, put them in a Mason jar with punched holes in the lid and a little grass. Kept a jar in my bedroom a few nights.
