Look-alikes
Often confused with the venomous Copperhead (Agkistrodon contortrix) due to color, but Copperheads have hourglass-shaped bands and vertical pupils. Also confused with Corn Snakes and Rattlesnakes.
Conservation Status
IUCN Least Concern. Threats include habitat loss and persecution by humans who mistake them for venomous species.
Cultural Significance
Mistakenly named 'Milk Snakes' due to an old folk belief that they sucked milk from cows in barns, though they actually enter barns only to hunt rodents. They provide excellent natural pest control.
Notable Features
Features a distinctive 'checkerboard' ventral pattern and smooth scales that feel waxy or polished to the touch. They are highly valued for their role in controlling rodent populations.
