In 2013, five rare butterflies, indigenous to Florida, haven't been seen in over six years. These include the zestos skipper, rockland Meske's skipper, zarucco duskywing, nickerbean blue, and the Bahamian swallowtail. The US Fish and Wildlife Service is reluctant to declare them extinct because other butterfly species have been "rediscovered" after long periods of not being seen by man.[8]
