|Scientific name||Lampropeltis leonis (Günther 1893)|
|English name||Nuevo Leon Kingsnake|
|Habitat||The western part of the distribution area of L. leonis consists of the area where the Chihuahua Desert borders the Sierra Madre Oriental.
Specimens of L. leonis are found in the Chihuahua Desert scrub, which is characteristic of that area, but also in somewhat humid habitats (Aramberri, San Juanito, Galeana). Occasionally these snakes are also found along the road between Doctor Arroyo and Galeana.
The eastern slope of the Sierra Madre Oriental is tropically humid and lushly overgrown thanks to the many rainfalls. The San Roberto Highway (Mex 31), which runs from east to west, from Linares to San Roberto, illustrates this vividly.
On the east side of this road, specimen of the tri-colour morph of L. leonis are found. The snakes are located on the road at night. They live here sympatrically with the Texan coral snake (Micrurus tener).
|Distribution||This species occurs in some northern parts of the Sierra Madre Oriental, especially in the states of Tamaulipas and Nuevo Leon.
In the far east of Coahuila, there are also specimen found. Animals are known from both the eastern and the western flanks of the Sierra Madre.
This species was formerly known as Lampropeltis mexicana thayeri. In terms of size, they do not differ much from the other species of the “mexicana complex”, though they are usually smaller than L. alterna. Adult specimen are usually between 60 and 75 cm long. The young are 20 to 25 cm long at birth.
When this species is fed excessively, they can be sexually mature at an age of about 24 months. When the animals are fed in a normal way, this takes place from about 32 months. The colours and drawing of L. leonis are very variable. See the photos you can see via google.
