Conservation
Least Concern (IUCN). Generally stable, though threatened by habitat fragmentation and intentional killing by humans.
Physical Description
Tan to coppery-brown base color with distinctive hourglass or 'Hershey Kiss' shaped dark brown bands that are wider on the sides and narrower across the spine. Head is broad, spade-shaped, and usually a solid coppery-pinkish color. Elliptical pupils.
Size & Dimensions
The specimen appears to be an adult, approximately 60-90 cm in length. Typical species range is 50-95 cm, with a maximum record of about 135 cm.
Habitat
Generalist species found in deciduous forests, mixed woodlands, rocky hillsides, and edges of wetlands. Often found near human habitations in woodpiles or debris. Elevation ranges from sea level to approximately 1,500 meters.
Diet & Feeding
Carnivorous generalist eating mice, small birds, lizards, frogs, and large insects (especially cicadas). They use an ambush hunting strategy, utilizing heat-sensing pits to locate prey.
Reproduction
Ovoviviparous (gives birth to live young). Litters typically range from 1 to 21 young, born in late summer or early fall. Juveniles possess a bright sulfur-yellow tail tip used for caudal luring.
Look-alikes
Commonly confused with Northern Watersnakes (Nerodia sipedon) and Eastern Milksnakes (Lampropeltis triangulum). Watersnakes have bands that are widest on the back, while Copperheads have bands widest on the sides.
Conservation Status
Least Concern (IUCN). Generally stable, though threatened by habitat fragmentation and intentional killing by humans.
Cultural Significance
Commonly encountered in North American folklore. Ecologically vital for controlling rodent populations and as a prey source for larger predators like Kingsnakes and raptors.
Notable Features
Features loreal pits (heat-sensing organs) located between the eye and nostril. Known for 'caudal luring' as juveniles, where they wiggle their yellow tail tips to mimic a worm to attract prey.
