Teinopalpus imperialis

The Kaiser-i-Hind "(Teinopalpus imperialis)", is a rare swallowtail butterfly found in Nepal and North Indiaand East to North Vietnam. 
The common name means "Emperor of India". The Kaiser-i-Hind is unmistakable and cannot be confused with any other butterfly. A predominantly green swallowtail, the male has a bright chrome-yellow patch on each hind wing.
The Kaiser-i-Hind is protected by the Law of India and Nepalese law. Protection enforcement in these countries is not effective, so it is hunted, and collectors pay high prices.
