Abstract Two Fabaceae in the Florida Keys, Pithecellobium keyense Coker and Guilandina bonduc Griseb., have been of interest because they are the larval host plants for the endangered Miami blue butterfly (Cyclargus thomasi bethunebakeri [Comstock & Huntington]; Lepidoptera: Lycaenidae). As a part of ongoing research and conservation for this butterfly, wild host plant material has been periodically collected in order to supplement a captive colony of C. t. bethunebakeri located in Gainesville, Florida, USA. In examining this plant material, 26 lepidopterans were detected, including several host records, a new continental record, and 2 likely undescribed species, 1 Aristotelia (Gelechiidae) and 1 Crocidosema (Tortricidae). Our results expand the geographic, life-history, and taxonomic understanding of lepidopteran herbivores that use P. keyense and G. bonduc in South Florida.
