DistributionRead full entry
Saltmarsh deer flies inhabit a range that is restricted to North America. They are commonly found along the eastern coast of the United States from Massachusetts to Florida. Specifically, they are most prevalent in the Carolinas; however, they can be found as far west as Mississippi. Their northern ranges are restricted to coastal areas because they are the only areas that offer the appropriate breeding habitats. These breeding habitats have supported isolated populations as far north as Maine.
