How do fireflies glow? The baffling bug mystery finally revealed
It took scientists 60 years of research to truly figure out how these bioluminescent creatures work. Until recently these cute little summertime beetles have been a strange and wonderful mystery.
They finally found the secret ingredient to how fireflies glow. And the results are pretty JAR-ing (just kidding, I mostly just wanted to use that pun).
If you were to make a firefly chemical reaction yourself, the recipe would look something like this: oxygen, calcium, magnesium, naturally occurring chemical called luciferin combined into a little box.
But they had yet to figure out the real combination of these ingredients in chemical form. Until now. And the missing ingredient that scientist just discovered: an extra oxygen electron.
