This non-venomous snake is recognized by its distinctive blue coloration, which can range from a bright sky blue to a deeper, more muted blue-gray. The Blue Garter Snake is a popular species among snake enthusiasts and researchers due to its unique color pattern and adaptability to various environments.

Physical Characteristics and Habitat

The Blue Garter Snake typically grows to an average length of 18-26 inches, with a maximum length of around 30 inches. It has a slender build and a distinctive stripe pattern, which includes a blue or blue-gray dorsal stripe, flanked by two yellow or white stripes.

Reproduction and Lifespan

Blue Garter Snakes breed in the spring, with males engaging in a complex courtship ritual to attract females. Females give birth to live young, typically between 20-50 snakes, after a gestation period of around 70-80 days. The young snakes are born with a length of around 6-8 inches and are independent from birth. Blue Garter Snakes can live up to 10-15 years in the wild, although the average lifespan is around 5-7 years.

Conservation Status and Threats

Blue Garter Snakes are listed as a species of least concern on the IUCN Red List, although their populations are declining in some areas due to habitat destruction, pollution, and climate change. The snakes are also vulnerable to road mortality, as they often cross roads in search of food or shelter. Conservation efforts, such as habitat protection and education programs, are necessary to ensure the long-term survival of this species.
