- Origin
- Southern Mexico to Colombia
- Protection status

- Brumation

- Cohabitation
- Keep them singly. Snakes are solitary and do not seek company — a shared hide is competition for the best spot, not social behaviour. The concrete reason is the feeding accident: if two animals grab the same food item, one can swallow the other along with it. On top of that, once they are kept together you can no longer tell which animal has eaten and which is losing weight. For breeding, put them together under supervision and separate them again afterwards.
Notes
A large tropical milk snake, split from the triangulum complex in 2014. Warmer and more humid than the North American species, and no genuine winter rest is needed.
