Definition

Noun 1. A nonvenomous North American kingsnake: The term "milk adder" refers to a specific, harmless species of kingsnake (Lampropeltis triangulum), often called the "milksnake." It is characterized by its tan and brown coloration with distinctive patterning.

Usage and Examples

• The milk adder is often mistaken for the venomous coral snake due to its similar banded pattern.
• Farmers once mistakenly believed the milk adder drank milk from cows, which is how it got its common name.
• If you see a milk adder in the wild, there is no need for alarm, as it is not dangerous to humans.

Advanced Usage and Notes

• The name "milk adder" is a regional and historical common name. In modern herpetology and general use, the snake is more accurately and commonly called a milksnake.
• The "arrow-shaped occipital spot" on the back of its head and the variation in stripe patterns (with southeastern populations having red bands) are key identifying features that distinguish it from truly venomous snakes.

Variants and Related Words

• Milksnake (n): The standard modern common name for the same species ().
• Kingsnake (n): The broader genus () to which the milk adder/milksnake belongs. Kingsnakes are known for being constrictors and for their immunity to the venom of pit vipers.

Synonyms

• Milksnake
• Scarlet kingsnake (specifically for the red-banded southeastern subspecies)
• Eastern milksnake

Important Clarification

• Not a True Adder: Despite the word "adder" in its name, the milk adder is not venomous and is not related to true adders (viper family). The name is a misnomer stemming from old folk beliefs.
• Mimicry: Its coloration is an example of Batesian mimicry, where a harmless species evolves to resemble a harmful one (the coral snake) for protection.
