Western Fence Lizard
The Western Fence Lizard (Sceloporus occidentalis) is a medium-sized, spiny-scaled lizard native to the western United States, distinguished by the vivid blue patches on the belly and throat of adult males.
Origin Story
First scientifically described in 1852 by Baird & Girard, the Western Fence Lizard is a wild species indigenous to regions including California, Oregon, Nevada, Utah, Idaho, and Washington. It has no known history of captive breeding origins, arising naturally within its native habitats.
Classification
Belonging to the genus Sceloporus within the family Phrynosomatidae, the Western Fence Lizard is part of the suborder Lacertilia, encompassing true lizards. It is closely related to other spiny lizards and fits within the broader order Squamata, which includes all lizards and snakes.
Appearance or Form
This lizard typically measures between 5.7 and 21 centimeters in total length, featuring keeled, spiny dorsal scales that give it a rough texture. Its coloration ranges from brown to gray or black, often with lighter stripes or patterns. Adult males are notable for their striking blue patches on the belly and throat, while females and juveniles display more subdued hues.
Behavior or Usage
The Western Fence Lizard is diurnal and highly agile, frequently seen basking on rocks, fences, and logs. It plays an important ecological role by feeding on a variety of arthropods, helping control insect populations. Notably, it contributes to reducing Lyme disease transmission by neutralizing bacteria in ticks that feed on it.

- Its spiny, keeled scales provide a distinctive rough texture.
- It can shed its tail (autotomy) to escape predators.
- It helps reduce Lyme disease by killing bacteria in feeding ticks.
- Several subspecies exist, adapted to different regions within its range.
🌍Habitat And Distribution
The Western Fence Lizard inhabits a variety of environments across its native range in the western United States. It is commonly found basking on rocks, wooden fences, and logs, favoring open, sunny areas where it can regulate its body temperature. Its distribution spans California, Oregon, Nevada, Utah, Idaho, and Washington, with several subspecies adapted to local conditions.

🍽️Diet And Feeding
This species is insectivorous, feeding on a diverse array of arthropods. Its diet includes insects and other small invertebrates, which it actively hunts during daylight hours. This feeding behavior helps maintain ecological balance by controlling insect populations in its habitat.
🦎Reproduction And Lifecycle
The Western Fence Lizard reproduces through egg-laying (oviparous), though detailed clutch size and breeding season information vary regionally. Individuals typically live between 5 and 7 years in the wild, progressing from juvenile to adult stages marked by the development of distinctive male coloration.
🛡️Conservation Status
Currently, the Western Fence Lizard faces no major threats and is not considered at risk. Its populations remain stable across its broad native range. The species benefits from its adaptability and resistance to colder temperatures relative to other lizards in the region.
🏡Pet Care And Husbandry
Though not commonly kept as pets, Western Fence Lizards can adapt to captivity with proper care. They require environments that mimic their natural habitat, including access to basking spots, appropriate temperature gradients, and a diet rich in live insects. Captive breeding is not widespread, and health issues are generally minimal when husbandry needs are met.
