Abstract

The Miami blue butterfly (Cyclargus thomasi bethunebakeri) is a state-endangered taxon in Florida and a candidate for federal listing. Here we report 12 polymorphic microsatellite loci appropriate for use in population and conservation studies. We genotyped 114 individuals sampled from a metapopulation in the lower Florida Keys over a 2-year period (2005–2006). These results show 4–14 alleles per locus, and ranges of observed and expected heterozygosities are 0.02679–0.79630 and 0.06154–0.69565, respectively. Large deviations from Hardy-Weinberg equilibrium (HWE) are observed across the whole sample set. When a single breeding population is analysed alone, seven of the loci are in HWE.
