.林至鴻-鱗粉上的小彩虹
(The Rainbow on the Butterfly’s Scale)

登山健行的途中,意外看到這隻小灰蝶,似白波紋小灰蝶又像琉璃波紋小灰蝶,翅膀原本是黑褐、青藍或藍紫色,但從這個角度,可看到光線在鱗粉上折射產生彩虹般的顏色。平時不容易見到這類小灰蝶展翅,尤其這般特殊的顏色。


Encounterthis little Lycaenidae butterfly while out hiking one day. It resembles the common cerulean (Jamides celeno) and also the dark cerulean (Jamides brochus).  The color of its wing was originally a shade of black brown, cerulean or indigo but from this angle the refraction of light has created a rainbow color on its scales. One usually does not witness this particular species extending its wings and definitely not of this color.
