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 ๐Ÿ˜†

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

It's been more than 20 years since my wife moved to the west cost and she still laments the lack of fireflies. Where-as, whenever I've been out east, I'm caught off guard by them... then I start singing Roxanne.

Firefly: a lightning bug

Lightning bug: a firefly

Fire bug: an arsonist

Lightning fly: ??? The electric eel of the dragonfly world?

That's no bat. Run!"

I saw a few lightning bugs in my yard last year. My life goal have them consistently in my yard. Good thing this dovetails nicely with my other life goals of getting butterflies, bumblebees and birds in my yards

Different areas have different lightning bugs too. The ones in southern ontario are not the same as the ones in the midwest US.

We used to have so many of them when I was a kid. Their numbers are dwindling. ๐Ÿ˜ญ

Saw this just the other day here...

[โ€“] [email protected] 29 points 2 months ago (10 children)

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.

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.

[โ€“] [email protected] 4 points 2 months ago (5 children)

I knew about them but didn't see them well into adulthood. It's underwhelming

[โ€“] [email protected] 14 points 2 months ago

Really? I'm a seasoned adult-er, and I still get a little flicker of wonder when i see those lights floating in the field behind my house on summer evenings.

Your mum is underwhelming.

Indeed, she doesn't shine at all

Bioluminescence is actual magic. I will take no calls on this matter.

[โ€“] [email protected] 7 points 2 months ago

Fuckin bio-lights how do they work

[โ€“] [email protected] 39 points 2 months ago* (last edited 2 months ago)

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.
