Snake diversity in the United States runs from south to north, with most southern states having the highest number of snake species. Maryland’s geographic situation on the Mason/Dixon line puts in in the middle of East Coast geography. It’s twenty seven snake species also puts it at the higher middle range of snake diversity among all US states.

This page presents a truncated version of Maryland states. Please press the green snake button for more pictures and information on a variety of snake species.

The picture at the top of the page shows a Black Racer (Coluber constrictor), a common species in Maryland. They are long, thin snakes with a black body, and as the picture highlights, white chins.

The term racer describes a behavior pattern often witnesses by people. When they are approached, the often race away very quickly.

Eastern Hognoses (Heterodon platirhinos) show a variety of body colors depending on their geographical location.

Kingsnakes and Milk Snakes

Almost everyone is familiar with the colorful kingsnakes and milk snakes. They are fairly popular in the pet trade and categorized as constrictors.

Humans need not worry, their popularity in the pet trade is an indication they are generally peaceful, nonvenomous snakes.

The picture under this heading shows the Eastern Kingsnakes (Lampropeltis getula). The log black body covered by a series of thin white bands down the back are the best identification clues.

picture of a Milk Snake
Eastern Milk Snakes (Lampropeltis triangulum) are also adaptable snakes, inhabiting multiples areas from fields to forests to farms. Finding Milk Snakes in the east can be as easy as taking a hike and flipping over a few big rocks or logs. The can grow up to on average about three feet in length and the red to orange to dull rust color of the bands makes them easy to spot.

About eight subspecies of Milk Snakes are described in the United States. Maryland hosts the more common eastern milk snake along with a subspecies called the Coastal Plain Milksnake ()Lampropeltis triangulum elapsoides)

picture of a Scarletsnake (Cemophora coccinea)
Now is a good time to also mention the Scarlet snake. As the picture shows, it’s easy to mistake the Scarletsnake (Cemophora coccinea) for a Milksnake or Kingsnake. They are a separate genera and fairly common in the Southeast.

A red face and red blotches surrounded by black bands are good field identification clues.

Yellow-bellied Kingsnake (Lampropeltis calligaster)

Two watersnake, the Northern Watersnake (Nerodia sipedon) and the Plain-bellied Watersnake (Nerodia erythrogaster), live in Maryland.

Of course many types of snakes swim in and/or bask near ponds and lakes. Nonetheless, when seeing a long and bulky snake basking near or swimming in the state’s lakes and ponds it’s always a good first guess to start with waternakes.

The snake’s body color changes depending on age and location. Usually the Plain-bellied Watersnake (Nerodia erythrogaster) is called the Red-bellied Watersnake, with a range limited to the lower Eastern Shore. All other watersnake finds in the state can be identified as Northern Watersnakes.

Rat Snakes

Rat snakes are the general name given to a group of constrictors that inhabit various regions of the East and Midwest. Their rodent diet and their propensity to inhabit areas with human populations often translated into the humans calling them rat snakes based primarily on the snake’s diet.

While many of the species have common names with rat snake included, other species are known as Corn Snakes and Fox Snakes. Their large size and fairly docile manner means there’s always talk about them in the reptile trade. Probably the corn snake is the most common of the species in the pet trade.

The Black Rat Snake ranks as the most wide ranging of the species. The all black body makes it a fairly easy species to recognize.

Maryland is also home to corn snakes (Pantherophis guttatus). They can be found in many of the state’s forest areas.

The picture highlights two facts. First the orange to red color explains a common nickname, red rat snake. Second, they, like other rat snakes are very good climbers. They climb trees primarily in search of bird prey. However, they can also fall prey to the large predatory birds such as raptors.
