 They spend most of their time hidden, emerging to feed on small rodents and lizards, but they have a particular taste for reptile eggs, swallowing them whole or puncturing them and consuming the contents.Mating of the northern scarlet snake occurs in March through June, with 3-8 eggs laid in mid summer, and hatching in early fall.Each hatchling is 13–15 cm (5-6 inches) in total length (including tail).
