Michigan researchers release 1,300 butterflies after species neared extinction in 2022

Researchers in Michigan have made significant progress in saving the Poweshiek skipperling butterfly, whose wild US population had collapsed to just nine individuals in 2022. Through a combination of captive breeding programs, habitat restoration, and carefully coordinated releases, over 1,300 butterflies were reintroduced into the wild in 2025. The recovery effort marks a dramatic turnaround for a species that was on the verge of disappearing entirely from the United States. Building on this success, conservationists have extended their work to other endangered butterfly species. The restored prairie habitats created as part of the initiative are also providing broader ecological benefits beyond the target species.
