This review applies to ALL import of insects into the US from any country even if it is just 1 bug or framed butterfly!
I have seen a large number of ebay members begining to buy insects from foriegn countries and it is very easy to get those really cool bugs that you have always dreamed about but there are a couple of things that you should know before you become an international insect buyer.

First you MUST obtain an import export license from the US FWS (fish & wildlife service) If you import, export, international travel, international mail, purchase from or sale to a foreign country, or other movement of insects across international borders, you must also obtain a USFWS permit. It is your responsability to check all the appropriate lists to determine if the insect is protected. The different lists do not include all common names for every listed species. In addition, in some lists, the scientific names of some species are not individually shown on the list or in a database. A number of the listings are not at the species level, If you do not find the species name on one of the lists, confirm that the species is not listed by contacting a permit office.
Then if you need to obtain a special permit get the application form for the law or treaty and activity you want to conduct & pay the application fee, if applicable. Some applications may require that you have a State or foreign permit before you can obtain a Federal permit.  Check the cites information of the foreign importing or exporting country to determine any additional requirements.
If you are applying for a protected species permit you will need to submit the application fee for the protected species permit.
IT IS YOUR RESPONSABILITY TO HAVE YOUR UNOPENED PACKAGE INSPECTED BY YOUR NEAREST USFWS INSPECTION STATION.

Remember you must first be a licensed importer.

The fines can be as steep as:
$1500.00 no import license
$500.00 per species for no FWS permit
$500.00 for no cites permit
And may include trials and even jail time in  some cases.

AND DON'T FORGET CUSTOMS Here is a little info from them...
Your Responsibility and Liability
The Internet has made it easy to find and purchase items from almost anywhere in the world. When goods move from any foreign country to the United States, they are being IMPORTED. Your great auction purchase of gorgeous butterflies? Depending upon the country of origin, quota restrictions could hold them up in CBP (customs border patrol) for a long time. And storage charges in such cases can be expensive. When you buy goods from foreign sources, you become the importer. And it is the importer - in this case, YOU - who is responsible for assuring that the goods comply with a variety of both state and federal government import regulations. Knowing what is admissible is just part of the story. The other part is knowing how to import. Depending upon what you are importing and its value, the procedures can be very complicated. It does not matter whether you bought the item from an established business or from an individual selling items in an on-line auction. If merchandise, used or new, is imported into the United States, it must clear CBP and may be subject to the payment of duty as well as to whatever rules and regulations govern the importation of that particular product into the United States.
It is your responsability to clear all imports through customs!!!

To sum it up it really is best to buy from a reputable source that has legally imported the insects. They may cost a little more or they might not have the "rare" bug that you want but there is probably a reason. Don't fall into the I'll just get it from overseas trap and especially not if the seller will ship it as a gift.

Importing without the proper license and permits is smuggling....
