Four-Lined Ratsnake

Wow! I was taking a photo of a beetle on a leaf when I saw this beautiful little Japanese four-lined ratsnake (shimahebi) lying on a branch about 50cm from my face! I thought it was a venomous Viper (mamushi) at first so I jumped. Anyway, I grabbed its tail and dropped it into an insect cage, so that I could take it home to show the kids. A very exciting morning.

According to the Japanese Ministry of Agriculture, the young of this species are often mistaken for vipers (mamushi) because of their similar patterning: http://www.maff.go.jp/nouson/mizu_midori/yougo/youda.html (in Japanese)
