North Carolina boasts a diverse range of snake species, and among them are several that exhibit striking black and white patterns. Identifying these snakes accurately is crucial, not only for appreciating their beauty but also for ensuring your safety and understanding their role in the ecosystem. This guide will delve into the common black and white snakes found in NC, helping you distinguish between them and understand their behavior.
What are some black and white snakes found in North Carolina?
Several snake species in North Carolina display varying degrees of black and white coloration. The most commonly encountered include:
-
Eastern Hog-nosed Snake (Heterodon platirhinos): This snake is known for its upturned snout and dramatic defensive displays. While coloration varies, many exhibit a pattern of dark brown or black blotches on a lighter, often yellowish or whitish background. This can appear almost black and white in some individuals, especially juveniles.
-
Eastern Milk Snake (Lampropeltis triangulum triangulum): This non-venomous snake is often mistaken for a venomous coral snake due to its ringed pattern. While the rings are typically red, black, and yellow/white, the color intensity varies geographically, and some NC specimens might have a pattern that appears more black and white, with subdued red tones.
-
Ring-necked Snake (Diadophis punctatus): This small, slender snake is usually a dark gray, brown, or black, with a distinctive bright yellow or orange collar around its neck. While not strictly black and white, the stark contrast between the collar and the body can create a black and white impression, particularly when viewed from a distance.
How can I tell the difference between these black and white snakes?
Distinguishing between these snakes requires careful observation of several features:
-
Size and Body Shape: The Eastern Hog-nosed snake is relatively stout-bodied, while the Eastern Milk snake is more slender. The Ring-necked snake is the smallest of the three.
-
Pattern and Coloration: Examine the pattern closely. The Hog-nosed snake has blotches, the Milk snake has rings, and the Ring-necked snake has a plain body with a distinct collar. Pay attention to the shades of black, white, and any other colors present.
-
Head Shape: The Hog-nosed snake has a distinctive upturned snout, unlike the other two.
-
Behavior: Hog-nosed snakes are notorious for their defensive displays, including feigning death. Milk snakes are generally more docile. Ring-necked snakes are secretive and often found under rocks or logs.
Are any black and white snakes in NC venomous?
No commonly encountered black and white snakes in NC are venomous. However, the Eastern Milk snake's resemblance to the venomous coral snake can cause confusion. Remember the rhyme: "Red on yellow, kill a fellow; red on black, venom lack." This is a helpful, but not foolproof, guideline. If you are unsure, it's always best to err on the side of caution and avoid handling any snake.
What should I do if I encounter a black and white snake in NC?
Observe the snake from a safe distance. Take a picture (if possible, from a distance) to aid in identification later. Do not attempt to handle it. If the snake is in a location where it poses a risk (e.g., near children or pets), contact your local animal control or wildlife removal service.
Where in NC are these black and white snakes most commonly found?
These snakes have varying habitats. Hog-nosed snakes prefer sandy or loose soil areas. Milk snakes are more adaptable and can be found in various habitats, including forests, fields, and near human dwellings. Ring-necked snakes prefer moist environments under logs, rocks, or leaf litter.
This guide provides a general overview. For precise identification, consulting a field guide specific to North Carolina herpetofauna is highly recommended. Remember, responsible observation and respect for wildlife are key to coexisting safely and peacefully with these fascinating creatures.
