Georgia, and Illinois. Reproduction Breeding of T. s. troostii takes place in spring, fall, and winter. The male and female go through a mating ritual in which the male "claws" at the female's face and his fore legs stiffen. The female then allows the male to mount. The females may go extremely far from the water to nest and are occasionally hit by cars while crossing roads. Females construct a nest, usually at night, in various soil types. Clutch size is six to 15 eggs with 71% of the females producing two clutches per year. Diet T. s. troostii is mostly herbivorous as an adult, but primarily carnivorous as a juvenile. The adults eat algae, fish, tadpoles, crayfish, seeds, plants, aquatic vegetation, insects, worms, and mollusks. This subspecies, like all aquatic turtles, can only swallow food when in the water.
