There are two recognized subspecies of S. dekayi found in Texas.
Adult Storeria dekayi typically measure 24-30.5 cm (9.5-12 in) in length,
Storeria dekayi is found throughout most of the eastern half of the U.S., with additional populations extending south along the Atlantic coast of Mexico.
Inhabiting moister habitats, Storeria dekayi is able to find and feed on insect and annelid prey, including insect larvae. Annecdotal accounts mention S. dekayi being found in open lots and fields in urban settings, though persistant pesticide use has eradicated most of these populations. Non-venomous, S. dekayi will not bite when picked up, but it may flatten its neck in a threat display.
Storeria dekayi is a live bearing snake, with mating occurring in the early spring and young born from June to August. The newly born juvenile snakes measure 7-11 cm (3-4.5 in) have pale collars around their necks, causing them to resemble ringneck snakes for a short period of their lives.
Storeria dekayi favors moist habitats, preferably under objects such as tin, wood and stones, or in habitats favoring moisture, such as canyons and bottom lands.
Dekay's brownsnake is not a protected species in Texas and can be legally collected with a hunting license.
In Texas, Storeria dekayi is found through most of the state, save the drier regions, such as the Panhandle and the Trans-Pecos.
