Hi Dr. Brown, 
In my experience, hand-carrying pinned insects on planes has not been an issue with TSA. I've done it several times since 2015, including international flights, with no concerns as I've always had the appropriate documentation.
You will still need to complete a 3-177 eDec before your departure, since what you'll be doing is still considered an export of material though. If you have any questions about this, please let me know. 
Sincerely, Shelby

Following up recent thread about form 3-177, I will be going to the European Congress of Lepidoptera in Italy this June.  I would like to hand carry some type specimens that I borrowed in the past. I have the loan forms to cover these types.  Does anybody know if there have been recent issues with carrying pinned specimens through TSA screening? I don’t think form 3-177 would be relevant to this.
