Eco-friendly lighting

Do you know what this is? You might have already guessed it from the title.






This is a Lighting Bug or better known as a Firefly, nocturnal members of the family Lampyridae.

Did you know that it is actually a beetle? Okay, now you know what it is but do you know how it produces the luminescence? Fireflies have dedicated light organs that are located under their abdomens. The insects take in oxygen and, inside special cells, combine it with a substance called luciferin to produce light with almost no heat. No batteries, no LED or bulbs! Imagine that. A safe way to produce lighting at no expense to the environment.




Firefly light is usually intermittent, and flashes in patterns that are unique to each species. There are over 2,000 species. Each blinking pattern is an optical signal that helps fireflies find potential mates.

It's just amazing all the different things nature has found a way to do. Who needs science fiction! - though science fiction is loads of fun too.

so did the camera flash exposure compensate the light from the firefly or the other way round? : p
