Monarch butterfly passes through Pittsburgh

October 5, 2026

A butterfly was observed in Pittsburgh on October 4, 2026. Monarchs migrate through the Mid-Atlantic during early to mid-October on their southbound journey to Mexican overwintering forests. The federal government has proposed listing the species as threatened under the Endangered Species Act, with a final determination now delayed until June 2030, leaving the species without Endangered Species Act protections during this critical migration period.
