Family
Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Colubrinae, Genus: Hemorrhois, Species: H. hippocrepis
Conservation
Least Concern (IUCN). Generally common throughout its range, though habitat loss and road mortality are localized threats.
Physical Description
Slender, agile snake with a distinctive pattern of dark rounded spots or 'horseshoes' outlined in white or yellow along a lighter grey or yellowish background. The head is distinct from the neck and features a dark band between the eyes and a horseshoe-shaped mark on the nape. Pupils are round.
Size & Dimensions
The specimen in the photo appears to be a juvenile or sub-adult, likely 30-50 cm. Adults typically range from 100 cm to 150 cm, with some reaching up to 170 cm.
Habitat
Favors dry, sunny, and rocky areas with scrub vegetation. Commonly found in Mediterranean-type shrubland, edges of cultivated fields, old stone walls, and sometimes near human dwellings. It ranges from sea level up to approximately 2,600 meters.
Behavior & Temperament
Diurnal and highly active. Known for being very fast and agile. When threatened, it is defensive and will not hesitate to strike or hiss loudly, though it prefers to escape into crevices or stone walls.
Diet & Feeding
Active forager specializing in lizards, small mammals, and occasionally small birds or other snakes. It uses its speed to chase down prey rather than relying solely on ambush.
Reproduction
Oviparous (egg-laying). Females lay clutches of 5 to 11 eggs in mid-summer, which hatch in late summer or early autumn depending on the climate.
Venom Profile
Non-venomous - no medically significant venom.
Look-alikes
Can be confused with the Montpellier Snake (Malpolon monspessulanus), though that species lacks the specific horseshoe markings and has a 'browed' appearance. Some color variants may resemble vipers, but the slender body and round pupils of Hemorrhois are diagnostic.
Conservation Status
Least Concern (IUCN). Generally common throughout its range, though habitat loss and road mortality are localized threats.
Cultural Significance
Ecologically beneficial as a predator of rodents and lizards. In some European regions, it was historically tolerated near homes because it was believed to keep mice populations in check.
Notable Features
Named for the unique horseshoe-shaped series of spots running down the back. It is one of the fastest moving snakes in the Mediterranean region and is an excellent climber.
