National Range: “southern Ontario, Michigan, Ohio, Indiana, and Illinois southward to Arksansas, Mississippi, and Alabama” (Hobbs Jr. 1989; F. fodiens); “Atlantic coastal plain, from Maryland to South Carolina” (Hobbs Jr. 1989; F. uhleri)
NC Physiographic Region(s): lower piedmont plateau and coastal plain
River Basin(s): all coastal plain river basins, and in the lower piedmont plateau sections of the Cape Fear, Neuse, and Tar-Pamlico (including a population on Roanoke Island, across Croatan Sound)
Adult Habitat: “lentic and lotic habitats and burrows” (Hobbs Jr. 1989); “Primary burrower along water courses and in low swampy areas. Often collected from lentic waters or sluggish streams during spring”(Bouchard 1974); “found in ditches ponds and marshes; usually constructs mud chimney above entrance to burrow…” (NHP ICAS 1999)
Juvenile Habitat: in heavy vegetation along banks or in swamps during spring; burrows?
Reproductive Season: winter?
Species associates: many

Notes: F. fodiens
- body shape: carapace slightly vaulted
- coloration: mottled tan, olive, or brown carapace with darker markings (sometimes with four dark brown longitudinal lines on dorsal abdomen, sometimes with with light yellow stripe on dorsal abdomen and black areola), underside cream
- spines: lacking
- rostrum: short, blunt, rounded
