Zephyrus
There are groupe of butterflies called Zephyrus.
Some of them actually have the name "zephyrus" as a part of their genus name.
Zephyrus is the name of the Greek God of Westwind.

I used the photographs I took from 1997 to 2000.
Most of them fly high among trees and it is rather difficult to take photos.
Some of them fly very early in the morning and some fly in the evening twilight.
