I do take them home and put them in alcohol- but just the auatics to document what is in a stream. I have a scientific collectors permit from Fish and Boat for most waterways in the Commonwealth, and I have a special permit from DCNR to collect on their land. Just learned I need one from game to collect on game lands, tho I have never collected on a game land.
Collections are considered 50 or more insects in possession, at least by fish and boat standards, and you need a fishing license to collect up to 50. Just a heads up.
