Schaus swallowtail
The range of the Schaus swallowtail has declined over the past century and has not been seen on the mainland since 1924. Habitat destruction, mosquito control, and hurricanes have reduced populations in the past. Captive bred individuals have been successfully released into the wild by researchers at the University of Florida to maintain the existence of this magnificent butterfly.
