Taxonomy
Baird and Girard described the species at 1853. Even the species-specific epithet,”marcianus” awarded in honour of this American Brigadier General Randolph B. Marcy, that at the middle 19th century directed surveying expeditions into the frontier.
There are just three subspecies currently known for its garter snake.
Northern Checkered Garter Snake (Thamnophis marcianus marcianus – Baird & Girard, 1853) – Located in the united states and northern Mexico. This subspecies is referred to as the Checkered Garter Snake of Marcy and is found at the pet industry.
Nicaraguan Checkered Garter Snake (Thamnophis marcianus bovallii – Dunn, 1940) – Located just in Nicaragua.
Yucatan Checkered Garter Snake (Thamnophis marcianus praeocularis – Bocourt, 1892) – This subspecies if located around the in Belize, Honduras, Guatemala and Yucatan Peninsula.
Venom
With impacts that they have toxins As with garter snake species. They’re deemed benign and dangerous to people, although their sting can create a response in people.

Conservation
Listed as”Least Concern” since those snakes are frequently dispersed and relatively standard at least in the northern portion of its scope. Back in North America, there aren’t any significant dangers to this Checkered Garter Snake, however they’re listed as endangered in Kansas.
But, subpopulations noise in southern Mexico and also Central America are endangered by habitat reduction for agriculture with the usage of pesticides resulting in declining amphibian populations these snakes feed .
As a result of this, the species is becoming less prevalent, and its own supply fragmented and disjunct in southern Mexico and Central America.
