Conservation in Action!

Limited to a single remaining population of less than 100 individuals, the Miami blue butterfly (Cyclargus thomasi bethunebakeri) is one of the most endangered insects in the world. Once locally abundant and widespread throughout south Florida, the species lost ground rapidly over the last few decades. By the early 1990’s, known populations were isolated and scarce.  Fear that the butterfly had gone extinct escalated until November 19, 1999, when the butterfly was rediscovered in Bahia Honda State Park in the Lower Florida Keys.  This small island of 524 acres, a flagship of the Florida Park system for its popular white sandy beaches and deep turquoise waters, is now the focal point of conservation efforts to save the last remaining Miami blues.

Owing to butterfly’s tenuous current situation, the Florida Fish and Wildlife Conservation Commission added the Miami blue to the state’s endangered species list in November 2003 providing the impetus for the start of an aggressive conservation and recovery effort.

Researchers from the McGuire Center for Lepidoptera and Biodiversity at the University of Florida have successfully reared the Miami blue in captivity, with the objective of increasing population numbers and releasing them back into the wild. Now some 28 generations old, the captive colony has produced more than 22,000 individuals. Wild reintroductions have begun in Everglades and Biscayne National Parks with plans to continue the release efforts through 2007. Learn more in Explore: Research at the University of Florida.
