The following butterflies of southeast Florida and the Florida Keys are considered to be rare, imperiled, on the decline, likely to be extirpated, or recently determined to be extinct – a classification offered by Marc C. Minno, Ph.D. who has closely studied this area’s butterflies over many years. Most of the species on Dr. Minno's list are found, as well, on the Florida Natural Areas Inventory's listing of imperiled species (www.FNAI.org).

This list represents approximately one-third of southeast Florida’s butterfly species.

It is sobering to understand that extinction and extirpation are in progress “under our very eyes” as we watch.
