Comments: HARMLESS (Non-Venomous) The Florida Scarlet Snake is locally abundant, but rarely seen due to its secretive nature. It lives mostly underground, in or under logs, or burrowed under tree bark. It is nocturnal and sometimes seen after dark crossing roads.
It feeds on small snakes, lizards, rodents, and reptile eggs.
It lays eggs. Breeding occurs from March through June, and typically 3-8 eggs are laid from May through August. Newborns are 5-6 inches (12-15 cm) in length.
Comparison with other species: The Scarlet Snake is often confused with the Scarlet Kingsnake (Lampropeltis elapsoides) and Eastern Coral Snake (Micrurus fulvius), but it is easy to distinguish between these three species look-alike species. The Scarlet Kingsnake (Lampropeltis elapsoides) possesses colored rings that go entirely around its belly. The Eastern Coral Snake (Micrurus fulvius) has a rounded black snout and its red rings touch its yellow rings.
