The color of this snake varies from yellowish-brown and reddish-brown to dark brown or gray. There is a weakly defined lighter stripe down the back with a row of dark spots on either side. Dark lines cross the back, connecting the dark spots on either side. The under surface is pale yellow, brownish, or pinkish with small black dots along the edges. The young are darker than the adults and the spotted pattern is almost invisible. Also, the young have a yellow collar across the back of the neck.
The closely related Northern Brown Snake is very similar in appearance, but it does not have the dark lines crossing the back and connecting the dark spots on either side. Also, specialists find differences in the number of scales along the under surfaces of these two snakes.
In Ohio, the Midland Brown Snake interbreeds with the Northern Brown Snake producing an intergrade that often has the combined characteristics of both parents.

Overall Range
Eastern Wisconsin and Michigan southward to the Carolinas and eastern Louisiana. Its distribution overlaps that of the Northern Brown Snake along most of the joint length of their ranges.

Range in Ohio
This snake lives in most parts of Ohio except for the unglaciated hills of the southeastern part of the state. Sometimes, as it does in Ohio, this snake interbreeds with the closely related Northern Brown Snake where their ranges overlap.
Midland Brown Snake

Local Habitat
This snake lives in moist to wet areas in woodland, prairies, marshes, and in the margins of swamps, bogs and ponds. In areas of human habitation it sometimes occurs in vacant lots and gardens.

Many of the Midland Brown Snakes often hibernate together during the winter. During mild weather they are diurnal, while in warm weather they are nocturnal. These are secretive snakes that hide under flat rocks, logs and trash.
