Night Snake (Hypsiglena torquata) is a nocturnal snake often seen crossing roads at night. The night snake preys upon lizards, small snakes, frogs, salamanders, and small mice, which it subdues with its mild venom; this venom poses no threat to humans. Young night snakes feed upon insects. If disturbed, the night snake raises its head and weaves, hisses, and flattens its neck in threat.
