The turtle, Chrysemys picta belIii, was studied in southwestern Minnesota. The taxonomic characteristics are analyzed. The turtles are diurnal and have an annual activity period extending from mid-May to October. Activity and feeding are controlled by water temperature. The population dynamics are discussed. Growth is rapid early in life but slows after maturity. Growth is compared with that of other subspecies of C. picta. Habitat preferences, predation, parasites, algal relationships and shell abnormalities are discussed.
