The Cold Light of the Firefly

This wonderful and yet small and tiny creature amaze me very much when I have seen them plaguing a tree and make that tree glow brightly in the dark after sunset. Its beautiful! Have you ever seen one like that before? Well, by reading this part of my blog you'll be amazed and awed to see not only the beauty but the wisdom on a firefly!

In tropical and temperate regions, the firefly is recognized by the flashing light it uses to atract a mate. Interestingly, the firefly's light is superior to the incandescent and flourescent light produce by man. In fact, the next time you look at your electric bill, think of waht this small insect can do.

An incandescent lightbulb emits only 10 percent of its energy as light; the rest is basically wasted, discharged as heat. A flourescent bulb performs much better, emitting 90 percent of its energy as light. But niether of these is a match for the firefly. With very few ultraviolet or infrared rays, the light emitted by this insect is nearly 100 percent energy effecient!

The firefly's secret lies in the chemical reactions of the substance luciferin, the enzyme luciferase, and oxygen. Special cells called photocytes use luciferase to trigger this process, with oxygen as fuel. The result is cold light - so named because it produces virtually no heat. Horticultural and environmental education Sandra Mason aptly remarked that lightbulb inventor Thomas Edison "must have been envious of fireflies."

What do you think? Yes, its really a small and tiny creature but yet a wonderful and magnificent insect in our planet. An unequivocal wisdom from nture.


LIGHT EFFECIENCY




INCANDESCENT BULB = 10%







FLOURESCENT BULB = 90%







FIREFLY = 100%
