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.

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.

I still see fireflies, but they're not as common as they were in my first 25 years. And I don't want to live in a world without fireflies! I just took a video of them to show my mom, she's in a different state and misses them. Thanks for this!

[@kirarhodes6111]

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

[@thomasdemilio6164]

I've just seen a firefly. It has been years since I last saw one

[@user-jt6ej7vh2p]

There were so many fireflies in my garden day before yesterday. 💡❤

[@girlonaswing9439]

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.

[@aquibalamLUMOS]

See that's why such drastic use of artificial lights are harmful. I understand lights at important places but these days we tend to glow almost all places with these dazzling lights. It really crushes the mood of the night. Can't we enjoy darkness for a bit and the magic that comes with it ?

[@DoNotForget45180]

I barely see them nowadays

[@finchwave]

I've never seen a glowing firefly. The only time I saw a firefly was when one flew into my bed at night. Not glowing. Just looking like a flying cockroach-

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.

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.

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

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 :)

[@milzambasith1250]

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

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.
