Fine hair

Celastrina sp.
A kind of Holly blue

Photograph by Baikada (ばいかだ)

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.

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.)

The hair of butterfly’s wing might be useful for something of not “Thermal insulation” purpose but “Flight”.
