Moon Fireflies HD Wallpaper

There are a number of different species of fireflies, none of which are actually flies—they’re beetles! They get the names “firefly” and “lightning bug” because of the flashes of light they naturally produce. This phenomenon is called bioluminescence, and the bioluminescent organs in fireflies are found on the underside of the abdomen. A similar group of organisms are glowworms. The term “glowworm” can refer to firefly larva or wingless adult females—some of which are not in the firefly family Lampyridae. Both glowworms and fireflies are bioluminescent. The important distinction is that fireflies have wings and glowworms do not.

Bioluminescence in fireflies is nearly 100 percent efficient, meaning that little energy is wasted to produce their light. By contrast, an incandescent light bulb is only 10 percent efficient—90 percent of the energy is lost as heat. For another comparison, the heat produced by a candle is 80,000 times greater than the amount of heat given off by a firefly’s light of the same brightness. Fireflies must be more efficient to save energy.

生物发光萤火虫是有效率接近100％，这意味着很少的能量被浪费掉，产生他们的光。相反，一个白炽灯泡只有10％的效率，90％的能量被丢失热量。对于另一个进行比较，由一个蜡烛产生的热量大于由相同亮度的萤火虫的光发出的热量大于8万次。萤火虫必须更有效地节约能源。</div> <div class="show-more-end">
