Overview
Ruthven's Kingsnake is a Mexican highland species known for its bold tricolor banding, which can resemble venomous coral snakes despite being entirely harmless. It belongs to the mountain kingsnake group found in the volcanic highlands of central Mexico.
It is one of several similar tricolor kingsnakes whose ring patterns vary regionally, making precise identification sometimes challenging without locality data.
How to identify it
- Bold rings of red or orange, black, and white or cream encircling the body
- Black bands typically bordered by narrow white or yellow rings
- Smooth, glossy scales and a rounded head
- Round pupils and a non-triangular head, distinguishing it from vipers
- Look-alikes: coral snakes and other tricolor kingsnakes; ring sequence and head shape aid separation

Inhabits pine-oak forests and rocky highland terrain at moderate to high elevations in central Mexico. It shelters under rocks, logs, and leaf litter in cool, humid montane environments.
Behavior, diet & reproduction
Primarily active at dusk and during cooler daytime hours in its highland habitat. A constrictor, it preys on small mammals, lizards, and other snakes. Reproduction is oviparous, with eggs laid in concealed, moist locations.
