What's Behind The Firefly's Glow | What's Inside?

The firefly is probably the Earth’s most famous bioluminescent species, with over 2,000 individual species. And the secret to its light comes from two essential components: luciferin and luciferase. But while the firefly may have evolved its lantern as a form of protection, today the lightning bugs use their light as a species-specific mating ritual. Here’s what really happens inside the firefly’s lantern.

I've finally understand now Fireflies are the real original firebenders, not dragons

[@thanthanh5190]

So who are the real original waterbenders?

Their light doesn't even produce heat...

I've always enjoyed fireflys! This is the best non-technical explanation I've seen. Thank you!

Fireflies >>>>>>>>> LIghtbulbs It really is interesting how efficient the firefly's lantern is!

Its restricting them from mating idk

Fireflies are incredible creatures, they’re like the light during the night.And it’s so awesome that it’s like small dots in the sky lighting up the dark nights.

[@hihihihi6156]

i remember kids catching them when i was a kid too, never saw one again in 15 years

[@LegalStolenAMVs]

Yeah man sad life ❤️ ( well I'm from India and I see them when I visit my Village it's beautiful ❤️)

[@divasv]

[@zarcadioszfraous2192]

People keep catching them and soon they're will extinct.

[@njdevil1525]

Damn it’s a shame you don’t see them anymore, I’m lucky I guess to see them every summer out on Long Island but deff not as much as it was when I was a kid.

[@BeautifulWolf1987]

It's sad that I don't see nearly the amount of fireflies (or lightning bugs as my kids call them) as I used to when I was a kid. I thought I was just imagining things. Now I know I'm not.

[@LegalStolenAMVs]

Sad man ❤️😢

[@alexsmith1207]

I never seen them since 2017 im wondering what happen to them? Climate change or chemicals?

[@LegalStolenAMVs]

@@alexsmith1207 bit of both 😐😔

[@dailydoseofmedicinee]

Last but not least, fireflies represent energy. Natural energy, and economic energy. But it also has the meaning of economy and efficiency because they use their environment in order to be as effective as possible and in order to gain their energy. Fireflies are fascinating little creatures.

[@LegalStolenAMVs]

❤️🔥 thq 💞

[@donnaohm1584]

I had never seen a firefly in my life until I was in my late 30's. It was amazing I was in awe like a child seeing something awesome for the first time. My colleague was having fun seeing my experience and laughing. You see I am from California and have never seen one in my entire life until that day...a most memorable experience nature is soooo cool.

[@cashway0420]

Same with me, I'm 34 and I saw one flying around my room as I was trying to fall asleep last night. I had no idea what it was so I crushed it because it was freaking me out, I feel bad now they are interesting insects.

[@BierBart12]

I live in a part of Germany that's supposed to have fireflies, but I've never seen one despite being outside a lot. I hope I'll see them someday

[@AverytheCubanAmerican]

You would not believe your eyes if ten million fireflies, lit up the world as I fell asleep

[@allthingsleah5182]

I wouldn't want to live in a world without fireflies too💖💖

[@milzambasith1250]

I wonder if the fireflies consciously adjust their light patterns like moving their hands or automatically like a heartbeat

[@hasitdawnedonyou]

For anyone who hasn’t seen fireflies before, please add it to your bucket list. It’s one of those experiences that changes how you see the world. Like diving

[@kachoww5981]

Eh I grew up catching them and does t change my world view much. I guess it depends on if we have the same world view

[@thestealth2448]

@@kachoww5981 maybe that’s because you grew up with them so it’s not special

Very simple and lucid explanation. Nature's beauties are truly magnificent! I didn't know that these little wonders were facing threats.

[@aleciamiaric8799]

This is sad. I have nieces and nephews that have not seen a firefly. ☹️

[@PaiviProject]

We don't have those in Finland and they are by far my favorite bugs here in USA. I enjoy watching them in the evenings. I feel bad that the numbers are declining :( I hope they never disappear I want to keep enjoying them as long as I can. Thanks :)

So your telling me it’s basically their lungs... like when we breathe in and out our lungs expand and contract just like there light turns on when they breathe in and turn off when they breathe out.

Modern light bulbs give off wayyyyy less heat

[@NKhoyKrStoutt]

The point is that fireflies give off virtually no heat.

[@ulisescarrillo3050]

It has been years since I saw a firefly , like 5 years at least, I don't think this generation will ever see one at this point

11 and when ever I was like, 5 6. Or 7, my dad used to take me outside. After I took a bath to catch fireflies with me in tonight, I caught one in a tiny little jar in fact, I caught 2 in my hands. It made me so happy to bring myself back to that memory, and then I was curious, how do they glow, So I came to this video.was very useful, I feel so happy inside

I see them all the time. In fact, I was just watching them and wanted to know how high they fly because some of the flashes were quite high up. I guess those are the males and the females were the ones close to the ground.
