#1. Western Whiptail
- Aspidoscelis tigris
- 2.5 to 5 inches long from snout to vent (length does not include the tail).
- Body coloring is gray-brown to yellowish, with dark bars or spots that form a web-like pattern.
- Skin folds are present on the neck, making the throat appear wrinkled.
- Rust-colored patches are often present on the sides of the belly.
You can find Western Whiptail Lizards in California in sandy, rocky, or firmly packed soil.
Their habitat preferences range from open forest to arid scrubland. Western Whiptails eat other lizards, scorpions, spiders, termites, and beetles. As you can see, this lizard is anything but picky!
Their physical characteristics and habitats are so varied that there are sixteen distinct subspecies! As you can see in the map above, five of the subspecies are present throughout the Southwest.
#2. Orange-Throated Whiptail
- Aspidoscelis hyperythra
- 2 to 2.5 inches long from snout to vent (length does not include the tail).
- The coloring of the dark fields varies from gray to reddish-brown and black.
- Light stripes run the length of the body.
- The top of the head is yellow-brown to olive, and the throat is orange, as its name suggests. In males, the entire underside is sometimes orange.
