Blanding's turtle is usually found in ponds, quiet streams, and other shallow bodies of water with thick vegetation and soft bottoms. It is an omnivore but prefers crustaceans (crustacean). Although a strongly aquatic turtle, it regularly basks in the sunlight during the spring. Females often travel long distances overland to find suitable nesting sites and typically deposit clutches of 6–21 eggs in early summer. Hatchlings emerge from their eggs by August or early September. They often overwinter in the nest and disperse during the early spring the following year.
