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

This bill designates the black swallowtail butterfly (*Papilio polyxenes*) as Michigan's official state butterfly. It creates a symbolic, non-regulatory change by formally naming this specific species in state law. The bill has no financial, regulatory, or operational provisions - it solely establishes a ceremonial designation. The change would take effect 90 days after enactment. This is a procedural resolution with no direct impact on policies, programs, or specific groups.
