Usually there are laws on the books to protect native species from capture. As well they are there to protect endangered or dwindling populations of certain species. Michigan? I am not sure of specifically which species are or are not on the list. Unless you are and can prove to the local wildlife protection agencies that your going to have the individual native species and or protected species in a educational/ science program most are disallowed. Wild caught reptiles are mostly problematic anyways with health issues and behavioral compexities. Better off with a nice captive bred IMO. Born free, live free.
