Experts thrilled as rare creature returns to US region

One of Michigan’s most endangered species, the Karner blue butterfly, appears to be making a comeback after being spotted in the Lower Peninsula.

As reported by Up North Live, the critically endangered species has been seen in and around the Muskegon River. The butterfly only lives in a few selected habitats and has suffered significantly because of the destruction and degradation of its native habitat, which has mostly been converted to agricultural land.
