Brown snakes feed on earthworms, slugs and salamanders.
Brown snakes are somewhat uncommon on the Savannah River Site.
This species is found in a diversity of habitats from moist to dry woodlands to swampy areas, if abundant ground cover and litter are available. Populations are frequently encountered in debris-covered sections of urbanized areas. This snake is one of the most common species in some residential areas of Georgia and South Carolina. This species is primarily associated with moist woodland areas with abundant ground litter. It is slender and seldom reaches a length of 1 foot.
