All i can say is INDIA: FORGET IT. http://www.theskepticalmoth.com/collecting-permits/ .I’m from India, btw. And trust me, you dont want to go through the maze of Indian biodiversity rules, restrictions, conditions and regulations on intercontinental transport.
Some years back I went to a butterfly farm in Suriname. Their core business was exporting butterfly dolls to European and American Butterfly gardens.
At the time it seemed like a very interesting business model. Due to the climate American and European butterfly gardens depend on a steady stream of new Dolls. I was told that the through put was a shipment per three weeks per butterfly garden. This specific farm had quite some species available.
It might be a solution to find these providers in various country. I was told that there are also some in Central America. These farms would not only be a good source for butterfly’s they might also assist you in import regulations, since they have to deal with them on a daily base.
If Suriname is not in reach, you could try to contact your local butterfly farm and inquire about their providers.
