Dekay's Brown Snake (Storeria dekayi)Species of Least Concern





Description: Dorsally, S. dekayi is brown to gray with a lighter center stripe bordered by small black spots; ventrally, it is lighter brown or pink with small black dots at the ends of the ventral scales. Adults usually measure less than 12 inches in total length (including tail), but the record total length is 19+3/8 inches. The dorsal scales are keeled, and it has no loreal scale. Females exceed males in snout-vent length and number of ventral scales while males exceed females in tail length, head dimensions, and number of subcaudal scales.


Habitat: S. dekayi is a lover of urban areas, and tends to frequent cities more often than the countryside. They can, of course, be found in areas such as wetlands, grasslands and forests, but they are most commonly encountered where humans are found. Moist areas are preferable habitats for them, which makes sense when you consider their favorite prey items.


Range: S. dekayi is native to Southern Ontario and Quebec, most of the eastern half of the United States, through Mexico, Guatemala, Honduras, and possibly El Salvador. More specifically, this common species inhabits most wetland and terrestrial habitats east of the Great Plains from sea level to 4,600 feet above sea level.

Diet: S. dekayi primarily feeds on slugs, snails, and earthworms. In the southern extent of its region the snake usually preys predominantly on earthworms, however, in the northern reaches of its range slugs are the predominant food source. It has specialized jaws that allow it to remove snails from their shells for consumption. Reports of other invertebrates (such as woodlice, mites, or millipedes) in the diet of S. dekayi are more than likely the result of accidental ingestion rather than intentional feeding, in which one of these invertebrates may have adhered to a slug or other prey item being consumed.


Reproduction: Like other natricine snakes such as water snakes (genus Nerodia) and garter snakes (genus Thamnophis), S. dekayi is a viviparous species, giving birth to live young. Sexual maturity is reached at two to three years. Mating takes place in the spring, after snakes emerge from brumation. Between 3 and 41 young are born in late summer.


Status: Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
