Top 30 Most Common Bugs In Florida (2022)

Which are the most common bugs of Florida? Florida has at least 12,500 insect species. They all eat something, and whether humans call them “pests” depends on how they impact our lives.

Some of them eat the plants we consider important, and some of them bite, sting, or try to feed on us. Many insects are considered invasive species that arrived in Florida by accident or were intentionally introduced. Many of the invaders affect Florida residents and its environment in a negative way.

The following is a sampling of the 30 insect species most common to our state.
