We present an account of flower-feeding by 2 species of mydas flies in Florida. We observed adults of Mydas clavatus and Mydas maculiventris feeding on flowers of both typical and unusually large (tree-form) Licania michauxii (Gopher Apple; Chrysobalanaceae). We also observed M. maculiventris feeding on flowers of Serenoa repens (Saw Palmetto; Arecaceae) in Florida scrub habitat. We discuss these observations following a brief review of feeding ecology in mydids, and include a checklist of the 12 known Florida mydids with a summary of our current knowledge of adult feeding in these species. We also provide additional sites of tree-form Gopher Apple in Martin County, FL, with a discussion of this unique form and the location of a new record-size specimen in Jonathan Dickinson State Park.
