|Scientific name||Lampropeltis polyzona|
|English name||Atlantic Central American Milksnake; West Mexican Milksnake|
|Distribution||The Mexican states of Colima, Guerrero, Hidalgo, Jalisco, Puebla, Michoacán, Oaxaca, Sinaloa, Sonora and Veracruz. It is believed that this species also occurs in Guanajuato, Morelos, Nayarit and western San Luis Potosí.|
|Habitat||I think you can say that most representatives of this species live in dry areas with many opportunities for shelter. It is often a bit moist under stones and other hiding places.|
|Details||This species is, amongst others, based on DNA research, “assembled” in 2014 from some, no longer existing subspecies of Lampropeltis triangulum. If you want to know more about this, read this article …

It concerns the following subspecies:
L. t. arcifera (Morelos, Guerrero, Michoacán, Jalisco, Western Querétaro – Mexico)
L. t. campbelli (Southern Puebla, Eastern Morelos, Northern Oaxaca – Mexico)
L. t. conanti (partially) (Sierra Madre del Sur in Guerrero, Oaxaca – Mexico)
L. t. nelsoni (Southern Guanajuato, Central Jalisco, Colima, Northwestern Michoacán, Tres Marias, Sonora – Mexico)
L. t. polyzona (partially) (Vera Cruz, Eastern San Luis Potosí, Tabasco – Mexico, Belize, El Salvador)
L. t. sinaloae (Southwestern Sonora, Sinaloa, Southwestern Chihuahua – Mexico)
L. t. smithi (Southeastern San Luis Potosí, Eastern Queretaro, Hidalgo, Northeast Puebla, Veracruz – Mexico)
All this means that the three most kept representatives of this species (L. t. campbelli, L. t. nelsoni and L. t. sinaloae no longer exist. Both now belong, like the five other representatives who are less or not kept in captivity, to the same species – L. polyzona.
This means that, for example, campbelli and sinaloae can be bred with impunity to each other. However, I would like to argue here not to do so and to keep both “types” pure.
After a brumation of 2 – 4 months, the reproductive cycle begins in the spring (March – June). About 30 to 45 days after fertilization, the female lays 2 – 20 eggs that hatch after about 60-65 days. The young are, on average 20 cm long at birth. Two clutches per year occur with this species.
This species is a just as opportunistic eater as most other kingsnake species in terms of natural food. This can, of course, vary per individual and “type”. The usual animals are on the menu (amphibians, reptiles and their eggs, birds and their eggs and rodents). Usually hunts in the late evening and night.
During the day, these snakes hide under stones, stumps, etc., and in rocky crevices or under cactuses. Where the snakes live in the immediate vicinity of human habitation, they are also found in barns, under houses, waste and piles of wood.
The average length of this species lies somewhere between 80 and 120 cm.For the appearance, you can click on the picture at the top of this page.
