A butterfly disappeared from Ontario in 1988 and has not been recorded there since

In an exciting conservation effort, scientists are set to reintroduce the frosted elfin butterfly to Ontario, a species that vanished nearly forty years ago. Adult butterflies and their eggs are being moved from New York for breeding in captivity before their release. The initial reintroduction is planned for spring 2027 in Port Rowan, where habitats have been carefully restored.
