This snake is endemic to the southeast of the United States. It is discontinuously distributed along the Coastal Plain from North Carolina to southern Florida (to Palm Beach County, Herp. Rev. 20:76), and west to eastern Louisiana (Mount 1975, Ashton and Ashton 1981, Dundee and Rossman 1989, Conant and Collins 1991, Palmer and Braswell 1995, Tennant 1997, Walley 1999, Ernst and Ernst 2003). It occurs mostly at elevations below 30 m and within 120 km of the coast (see Ernst and Barbour 1989).
