The bill H. B. No. 2025-2026 proposes to enact a new section in the Revised Code of Ohio, specifically section 5.035, which designates the Zebra Swallowtail butterfly, scientifically known as Eurytides marcellus, as the official state butterfly of Ohio. This legislation aims to recognize and celebrate the Zebra Swallowtail as a symbol of the state's natural heritage.

The bill includes new legal language that establishes the Zebra Swallowtail as the official butterfly, thereby formalizing its status within Ohio's state symbols. There are no deletions from current law associated with this bill, as it introduces a new designation rather than modifying existing statutes.
