Not even reaching two feet in length as a grown adult, the Florida scarlet snake, Cemophora coccinea coccinea, is a small and reclusive non-venomous snake. As is the case with the Scarlet kingsnake (Lampropeltis elapsoides), the Florida scarlet snake is often confused with the venomous Harlequin coral snake (Micrurus fulvius) because of its tri-colored patterning. They spend the vast majority of their time hidden under debris during the day and typically only come out of hiding at night. It’s not entirely uncommon to find Florida scarlet snakes patrolling the edges of backwoods highways throughout the central Florida night.
