State: symbol; Karner blue butterfly; designate as the official state butterfly. Creates new act.

HB 4601 designates the Karner blue butterfly (*Plebejus melissa samuelis*) as Michigan's official state butterfly. The bill directly affects the state by formally recognizing this specific butterfly species through legislative action. It creates a new statutory provision requiring the Karner blue butterfly to be recognized as the state's official butterfly, effective 90 days after enactment. This is a symbolic, non-regulatory designation with no fiscal impact or policy changes beyond the official recognition.
