FLORIDA KEYS Occurrence: A Doubtfull Record

Florida Keys History and Distribution: Not reported for the Florida Keys by John Kunkel Small in 1913. Reported for Great White Heron National Wildlife Refuge (Weiner, 1980) and Dry Tortugas National Park (Stoddart & Fosberg, 1981 in Reimus & Robertson, 1997), but there are no vouchers or other observations for the Florida Keys. Probably misidentifications of A. flavescens or A. maritima.
