How to Identify the Louisiana Milk Snake (Identification Guide)

Key identifying features

The Louisiana Milk Snake (Lampropeltis triangulum amaura) is a small, non-venomous subspecies of milk snake with a vivid tricolor pattern, smooth scales, and a head barely distinct from the neck, typical of the species.

Coloration & pattern

This subspecies displays red or reddish-orange bands bordered by black, separated by narrower white or pale gray rings that fully encircle the body. The bands tend to be somewhat narrower than in some other milk snake subspecies, and the black bands are often prominent and well defined. The snout is typically black, followed immediately by a pale band.

Head, eyes & scales

The head is small and rounded, not noticeably wider than the neck, with round pupils and moderate-sized eyes, both hallmarks of non-venomous colubrids. Scales are smooth and glossy throughout, giving the banded pattern a polished sheen.

Size & body shape

Adults are relatively small for the species, generally 40–70 cm (16–28 inches) in length, with a slender, cylindrical body and a moderately long tail. Juveniles show the same banded pattern as adults, often with slightly more vivid coloration.

Range & habitat where you'll see it

This subspecies is native to Louisiana and adjacent parts of the Gulf Coast, including eastern Texas and western Mississippi, inhabiting pine woodlands, bottomland hardwood forest, and areas near swamps or wetlands. It is secretive and largely nocturnal, often found under logs, bark, or debris.

How to tell it apart from look-alikes

As with other North American milk snakes, the key identification point relative to venomous coral snakes present in overlapping regions is that red bands border black bands, not yellow. Its relatively small size and narrower bands compared to some other milk snake subspecies can help with more precise identification, though locality remains the most reliable clue. Smooth scales and round pupils separate it from any venomous pit vipers found in the same wooded habitats.
