Canada to US?

[livingplanet3]

I'm in the US, and would like to purchase a single, non-CITES butterfly specimen from a dealer in Canada. Would there be any special paperwork involved for such a transaction? It seems I read somewhere that (at least, in past times), paperwork was only required on the US end when importing a large number of specimens for commercial purposes (unless CITES species are involved, of course). Because they are intracontinental countries, are the rules for insect specimen exchanges between Canada and the US different in any way than those for intercontinental countries?

It's not exactly the same thing, but whenever I've sent anything to Canada, I still have to fill out customs, just like it was going to the EU.
I'm sure someone else has experience with this, and it'll be interesting, now and then I see Canadian offerings, and just bleep right past.
