Overview
The tropical milk snake is one of many regional forms within the wide-ranging milk snake complex, occurring from Mexico south through Central America. Its bold tricolor banding provides classic Batesian mimicry of coral snakes sharing its range.
It is a constrictor that helps control rodent and reptile populations in the varied habitats it occupies.
How to identify it
- Bands of red, black, and yellow (or white) encircling the body
- Black snout, unlike the often red or pale snout of true coral snakes
- Smooth, glossy scales
- Round pupils and a narrow head barely distinct from the neck
- Band pattern and sequence vary regionally but always lack the true coral snake's red-touching-yellow rule in this species' local mimicry pattern

Inhabits a broad range of environments including tropical forest, forest edge, agricultural land, and rocky hillsides from lowlands to moderate elevations across Mexico and Central America.
Behavior, diet & reproduction
Primarily nocturnal and secretive, sheltering under logs, leaf litter, and debris by day. A constrictor that feeds on lizards, small mammals, and other snakes. Egg-laying.
