Because of Florida's climate (and especially the tropical climate of Southern Florida), the state has a plant profile very different than the rest of the United States. As a result, many psyllids that are widespread throughout temperate North America are absent here, instead replaced by many interesting species that are found nowhere else, including both undescribed endemics and species that have been introduced from the tropics. This list includes hosts for both native and introduced psyllid species which have been recorded from Florida, or are expected to occur there.
