Conservation
IUCN Red List status is Least Concern, due to a wide distribution, high adaptability to human-altered environments, and large stable populations.
Physical Description
Features a yellowish to brownish ground color with four distinct dark longitudinal stripes running down the length of the body. The head is relatively distinct from the neck, eyes have round pupils, and the scales are weakly keeled.
Size & Dimensions
The specimen shown is likely a sub-adult or adult, approximately 3 to 4 feet in length. Typical adults range from 90 to 180 cm (36 to 72 inches), with record lengths exceeding 200 cm.
Habitat
Found in a wide variety of habitats including pinelands, hardwood hammocks, swamps, agricultural fields, and suburban areas. Highly adaptable and often arboreal, frequently utilizing trees, abandoned buildings, and structures.
Diet & Feeding
Primarily feeds on rodents, birds, bird eggs, and bats. It is an active forager and proficient climber that dispatches prey using constriction.
Reproduction
Oviparous, typically laying clutches of 12 to 20 or more eggs in early summer within decaying vegetation, hollow logs, or loose soil, where they incubate for about two months.
Look-alikes
Can be confused with other rat snakes in the Pantherophis complex, such as the Central Ratsnake (Pantherophis alleghaniensis) or Everglades Ratsnake (Pantherophis alleghaniensis x quadrivittatus intergrades), which may show blotched patterns instead of distinct stripes depending on geographic intergrade zones.
Conservation Status
IUCN Red List status is Least Concern, due to a wide distribution, high adaptability to human-altered environments, and large stable populations.
Cultural Significance
Highly beneficial to agriculture and human settlements due to their efficacy in controlling rodent populations, leading them to frequently inhabit barns and outbuildings.
Notable Features
Known for their exceptional climbing ability, allowing them to scale vertical brick walls, trees, and rafters with ease. They can also produce a musky secretion or kink their bodies into an S-shape when threatened.
