No fireflies where I live, but that doesn't mean my childhood was free of a beautiful insect swarm.
My area had a bad outbreak of cockchafers I got to enjoy.

And an equally beautiful name for that fine insect
Is no one going to point out that it looks like Sauron's eye between the index and middle fingers?
I grew up calling them lightning bugs, and I'm so excited to see a thread full of people calling them the same!
In German, they're Glühwürmchen ("glow worms").
Wait hold up, in Dutch we have glimwormen ("shimmer worms" ) but those don't fly! They're actual bioluminecent worms.
Aren't German Glühwürmchen the same thing?
Fireflies is a much cooler name though.
My mom grew up in an area of California with no fireflies. When she was a teenager, she went on a cross-country trip with a friend. In the mountains of North Carolina, they were driving along at night when some bugs hit the windshield of their car. They didn't think much of it... until the bug guts started glowing. Then they screamed.
We used to have so many of them when I was a kid. Their numbers are dwindling. 😭
Saw this just the other day here...
The less I maintain my yard the more lightning bugs we get.
We do not maintain our back yard very well. I refuse to let these amazing insects disappear. We also seed for pollinators as well.
I tried to go this route with my small backyard. Unfortunately invasive vines (creeping Charlie and English ivy) got entrenched in very short order and outcompeted almost everything else. Pulling up the vines left nearly bare earth that eroded very quickly. If I ever get the money and the time, I'm going to have to add soil and seed and tend to it properly. For the time being, I left most of last season's leaves (mostly oak) and put down netting is some of the worst areas to try and keep the wind from stripping it bare(er). I'm hoping this leads to better water retention and soil conditions, and not just hiding spots for more vines. 😕
I saw that the other day too. It's just that 35 years ago, everyone still raked their lawns. Same as 35 years before that.
We are in the middle of an insect apocalypse.
Remember when you were little how many fucking moths there were? Couldn't keep the porch light on at night or they'd get in the house and you'd be finding moth carcasses all summer.
Now there's just a few. Hardly see any anymore.
Same for house flies, and bees. I used to have to go and spray for wasps every spring, I don't remember the last one I saw.
i tell this to people all the time and they do not believe me
Grasshoppers too. I used to fill buckets with them as a kid. I haven't seen more than a few in the last decade.
Remember when you needed a bug shield to drive on the highway?
Yes and yes (to the person you replied to). All I'm saying is that that narrative seems to be coalescing around "it's because people raked leaves." Does that play a part? Probably. But there's no way it's just that. It's far too pervasive to be "personal actions." The root cause has to be systemic.
It's also humans continually expanding and building in previously undeveloped areas. It crowds out other species.
30 years ago it didnt matter if you raked your leaves because there were still plenty of areas for lightning bugs to migrate in from. But when everyone's surrounded by miles of suburbs the lightning bugs have further to go for you to see them
People have been raking leaves the whole time, so that's definitely not why.
It's not just the leaves, it's humans fucking with the environment, on a macro and micro scale. But that's harder to convey in a single panel
Agreed. But as someone who grew up with the Crying Indian, I am very wary of this kind of oversimplification. It was always, "make sure to cut the rings from the six pack of cans so the turtles don't get stuck," and not, "stop manufacturing death traps," or, Primus forbid, "stop treating the ocean and waterways in general like free waste disposal." It's still being actively astroturfed to this day (see also plastic straws). Case in point: a few years ago there was an "accidental chemical waste discharge" into a tributary of a major regional river that is used as a water source for much of the area. This was posted about in a lightly trafficked regional subreddit where a "hot" post might accumulate a few dozen upvotes over the course of a day and a handful of comments. This one reached over a hundred comments within hours.
It's only x gallons, the river moves y gallons every minute. Nobody would have noticed until the media made a big deal."
The same stuff is used in cosmetics and people put it on their face every day. It's harmless.
And so on.
Messaging is important. The corporate class understands this. Hence trying to shift blame for every single systemic issue onto individuals. Plastic straws. You don't have the right to swim in clean water. Plastic bags. Fuel efficiency. Overnight delivery. Vote with your wallet. Overproduction. Recycling. And now raking leaves.
Want all that in a single panel? Zoom out from the raked lawn and show the silhouette of a factory belching smoke into the air and vomiting waste into a river in the background.
Bioluminescence is actual magic. I will take no calls on this matter.
Humans are bioluminescent, too! But it's too dim for anything to actually be able to see, so it's no fun.
Is that "article" trying to say we're exothermic and thus glow in the infrared?
Magic exists but we call it science
Any sufficiently advanced magic is indistinguishable from science.
Hell ya. Real magic is the feelings we felt along the way. Swimming in bioluminescent waters is one of my favorite life experiences
Nah, it legit is, though. Just because someone or most someones understand how something happens doesn't mean it isn't magic anymore. It just means that we have a hard magic system. We understand our magic so well that we've stopped seeing it as magical, but if you take a step back and take a look at the big picture it becomes clear that the world is magical, and everything around us is this amazing, often confusing, incredible tapestry of Wonder and awe. The world has just ground us down so much that we feel like wonder is strictly for children, that we're not allowed to feel wonder anymore. Embrace the magic. Even if you know how it works.
Eh, what fireflies can do is kinda the base level of the bioluminescence 'skill' of the evolutionary tech tree.

Humboldt squid skin is bioluminiscent, but roughly akin to a flexible lcd or oled screen, with many different 'pixels' capable of being set specifically.
They likely have the ability to communicate by basically displaying different patterns of different colors and brightnesses and translucency, sorta like a human walking around with a sandwich board made of lcd screens, which they can control with a phone app.
They may very well have an entire language they can convey via sequenced or at least specific patterns.
Note: No clue if you can actually trace bioluminescence in fireflies and certain cephalopods to the same common ancestor or if its completely different, independent evolutionary occurances, but my point is there are certainly more and less complex and utility granting forms of bioluminescence.

"Nat 15. Your abdomen glows and dims slowly and rhythmically."
Pathfinder 2e literally has bioluminescence bombs that's just jarred firefly juice that's secreted by humanoid fey that resemble the bugs
Spelling it without help is also magic, so I hear ya.

Also, people are born every day, and some just go on with their lives never learning about random facts like these. Every day, someone is one of the lucky 10k.
Man, imagine seeing a field of fireflies IRL for the first time, if you had never heard of them before! That would be pretty mindblowing.

these guys are great!
I was also blown away the first time I've seen bioluminescent bacteria on some strip algae...you would pass your finger by them and see the hidden binary encoded alien messages
Tried searching YouTube for "fireflies" to watch them in action. 99.9% of the results are music, podcasts and political channels using the term. Think I saw 2 videos of actual fireflies on the first page of results 😆
Firefly: a lightning bug
Lightning bug: a firefly
Fire bug: an arsonist
Lightning fly: ??? The electric eel of the dragonfly world?
"Is that bat glowing?"
That's no bat. Run!"
