ルリシジミの仲間は、日本では比較的よく目にすることが出来ます。
小さい割に、素早く飛び回るので接写できるチャンスは少ない昆虫です。
You might be able to see A kind of Holly blue comparatively well in Japan. They quickly fly about by a small body. Therefore there is few me in the chance that can take a close-up photograph with them.

写真を見ると、羽にたくさんの細かい毛が生えています。
よく考えてみると、昆虫にも毛が生えているものがたくさんあるのですが、
毛は鳥や哺乳類の特徴のような気がしてしまっていて、
昆虫のような無脊椎動物に生えているとちょっとびっくりします。
(カブトムシのような甲虫でさえも、背中には毛が生えていますね。)
A lot of fine hairs have grown in its wing when this photograph is seen. There are a lot of things which hair grows to other insects. However, I have a feeling that hair seems to be a bird and a mammalian characteristic and am surprised a little when hair grows to the invertebrate including the insect. (Even with a Japanese rhinoceros beetle (Trypoxylus dichotomus) such as the beetle, hair grows to the back.)

蝶の羽の毛は、「保温」目的ではなくて、「飛翔」の何かに役立つんでしょうね。
The hair of butterfly’s wing might be useful for something of not “Thermal insulation” purpose but “Flight”.
