The main checklist is a list of Florida lepidoptera organized by family and then by genus and species names. There are links to two other lists for reference at the top of the checklist page. One is a list of the common names of all Florida leps. The other is a list of species names, arranged alphabetically by species. For instance, Hyles lineata is found under lineata, along with Diastema lineata and Schinia lineata. http://www.fsca-dpi.org/Lepidoptera/LepidopteraFrame.htm
