Here is a list of swallotail butterflies I jus found out about while doing some research:
Swallow Tail Butterflies ( Papilionidae ):
Malabar Banded Peacock - Papilio buddha
Royal Swallowtail - Teinopalpus imperialis
Note: This is one of the species that does have Papilio in their latin name.
This is what the site had to say about Teinopalpus imperialis:
This magnificent butterfly ranges from Nepal - Sikkim and Assam
through the Naga and Chin hills into Burma and on into Central China.
The female is much larger and rarer then the male- the latter being some what
brighter coloured with a large yellow area on the upper and undersides of the hind wings.
The flight is fast and powerful and the butterfly inhabits forest areas between 5000- and 10,000 feet. Wing span approx 3 ( male ) and 4 ( female ) inches.
Now I find that very interesting. Don't you?
