I found this caterpillar last year (Sep 4th, picture above) in my
garden. When I did some digging in May this year I found the nymph (May
10th, picture left) about 3 meters from where I had seen the
caterpillar. According to advices over the internet, I kept the nymph in
a glass inside the house. The full butterfly evolved on June 10th. I was
surprised by its beauty. I had leaned some sticks into the glass before,
so that it could climb up. It rested on the hazel-stick the whole day
and flew away at night.
