DeKay’s Brownsnakes are always brown or grayish-brown. They have a wide light brown stripe down the center of the back. On each side of the stripe, there are black spots that are sometimes in the form of a checkerboard pattern. Their underside is white or tan. They have a black spot on the top of the head, black sideburns, a black spot under the eye, and black parentheses on each side of the neck. They are usually about 1 foot long (the longest documented in Vermont is 17 inches) with keeled scales. When very small, they have a white ring around their neck that extends forward and under the eyes. Even when very young, they have the same pattern of black spots on the head and neck.
