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

HB 4054 designates the monarch butterfly (*Danaus plexippus*) as Michigan's official state butterfly. This symbolic bill directly affects all Michiganders by adding a new state symbol to official state emblems. The key provision (Section 1) formally replaces any prior designation with the monarch butterfly, requiring state agencies and official materials to recognize it as the state butterfly. The bill has no financial impact or regulatory changes, as it is purely a ceremonial designation.
