Is it legal to travel places and collect bugs and butterflys and such and sell them somewhere. where?

Question

i'm not talking about capturing animals like monkeys by the way

Answer 1

as long as you dont take them out of the country or bring it into the country and your not trespassing on someones private property is it perfectly legal

Answer 2

Are you talking about traveling outside of the U.S. and then bringing them back into the U.S. to sell?  If so, no ... that's not legal.  We went on a cruise last year and I was told I couldn't even bring a few little seashells I'd collected on a beach in St. Maarten back into the U.S.
