The term missouri black snake often evokes images of a long, dark form slipping through leaf litter or tall prairie grass. In the Show-Me State, this phrase typically refers to several species of non-venomous colubrid snakes, most commonly the Black Rat Snake, also known as the Pilot Black Snake. These reptiles are a vital part of local ecosystems, acting as natural rodent control and serving as both predator and prey in a complex food web. Encounters in backyards, barns, and along hiking trails are frequent, prompting questions about identification, behavior, and safety.
Identifying the Missouri Black Snake
Proper identification is the first step toward understanding these animals. The Black Rat Snake is the species most people mean when they use the colloquial name missouri black snake. As an adult, it is typically a deep, glossy black with a white chin and throat, and some older specimens may develop a faint white pattern on the scales. Younger snakes often display a starkly different pattern of gray blotches on a brown background, which gradually darkens as they mature. Adults can reach impressive lengths of six feet or more, with a robust body and keeled scales that give the skin a ridged appearance when stretched in the light.
Distinguishing from Venomous Look-alikes
Fear often stems from confusion with venomous species, but the actual risk posed by the missouri black snake is minimal. The primary look-alike in Missouri is the Northern Copperhead, a venomous pit viper. Key differences are immediately apparent upon close inspection. Copperheads have hourglass-shaped saddles, are generally a tan or coppery color rather than black, and possess elliptical, cat-like pupils. Furthermore, copperheads are much more sluggish and tend to hold their bodies lower to the ground. Black Rat Snakes are constrictors, moving with a powerful, straight-line purpose that is far more dynamic than the typical viper movement.
Behavior and Habitat
These snakes are diurnal hunters, meaning they are most active during the day, particularly in the cooler morning and late afternoon hours. They are exceptional climbers and are frequently found scaling the trunks of mature trees in search of bird nests, where they consume eggs and fledglings. On the ground, they patrol the edges of fields and forest lines, feeding on mice, voles, and other small mammals. When threatened, they often freeze, relying on their excellent camouflage, but if cornered, they may vibrate their tails rapidly against dry leaves, creating a sound that mimics a rattlesnake—a clever defensive bluff.
The Ecological and Practical Benefits
Beyond the immediate shock of an unexpected encounter, the missouri black snake provides significant ecological and practical advantages. By preying on rodents, they help stabilize populations that can damage crops and spread disease. They also consume insects, frogs, and even other snakes, including venomous species, maintaining a balance in the local environment. For homeowners, the presence of these snakes in barns or outbuildings is essentially a form of natural pest control, reducing the need for chemical traps and poisons that can harm pets and children.
Safe Handling and Coexistence
While non-venomous, the missouri black snake is a wild animal that will defend itself if handled improperly. The best course of action is to leave the snake alone, allowing it to move on its own. They are generally shy and will retreat if given an escape route. If a snake must be removed, it is recommended to contact a professional wildlife removal service. Attempting to kill the snake is discouraged, as it is illegal in many municipalities and disrupts the natural balance of the area without solving the root issue of attracting rodents.
