中文注释:放大15倍后,这张毛茸茸的脸破坏了蛱蝶的美丽形象。角状的触须充当了其味觉、触觉、听觉和嗅觉的传感器。蛱蝶带有斑点的眼睛由成许许多多微小晶状体构成。这双眼睛使它看到人类看不到的由饱含花蜜的花朵发出的紫外线,从而引导蛱蝶找到这些花朵。为了吸到深藏在花中的花蜜,它会舒展现在正蜷曲在两眼之间的长长的中空的口器。照片为《国家地理杂志》1968年4月刊“欢乐谷的自然天地”一文而摄 作者: Paul A. Zahl    来源:http://www.cnnas.com 《国家地理》杂志
蝴蝶 快乐谷 马里兰州 图片故事:高清壁纸:英文注释:Butterfly Tongue, Pleasant Valley, Maryland, 1968A bewhiskered face, here magnified 15 times, belies the beauty of a nymphalid butterfly. Hornlike antennae serve as taste, touch, hearing, and smell sensors. Blotchy eyes with hundreds of minute lenses guide the butterfly to nectar-bearing flowers whose colors give off ultraviolet rays visible to the insect but not to humans. To reach nectar buried deeply in blossoms, it uncoils its long, hollow tongue, now tucked between its eyes.
