Have you seen these lizards scurrying around the South Bay?

The Western Fence Lizard (Sceloporus occidentalis), also known as the blue-belly, is the most common lizard in Southern California due to its prevalence in populated areas and its high visibility.

The Common Side-Blotched Lizard (Uta stansburiana) is another resident species, particularly in sandy, rocky, and bushy terrain.

Their diet primarily consists of ants, beetles, flies and caterpillars, though they may also consume spiders, grasshoppers, centipedes, and ticks. 

Western fence lizards are  beneficial,  consuming insect pests and neutralizing the Lyme disease-causing bacteria in ticks. The presence of Western fence lizards can be an indicator of a healthy, balanced ecosystem, as they require a balanced food source and a healthy habitat.

SBPC volunteers spot these lizards on a regular basis at local restoration areas, such as the Esplanade Bluffs and Hopkins Wilderness Park. Last week at Madrona Marsh Preserve there was a relatively large group of lizards next to and on the trail near the nursery - and they did not scurry off as the volunteer approached. Noting this to be an unusual behavior, the volunteer investigated more closely. There were about a dozen of the little rascals scurrying about in smaller groups - clustered in small groups with each individual focusing on a central point. It appeared to be a feeding frenzy! Sure enough, insects emerged from a small hole in the ground at the focal point within the group. As quickly as one squeezed out of a hole, a watchful lizard snatched it up, and chomp, chomp, gone! No wonder they did not flee at the approaching volunteer. Food trumps fear!

Madrona Marsh Docents and visitors joined the observation party and enjoyed nature in action. The volunteer was then able to consult the forensic entomologist David Faulkner, and Professor Jeanne Bellemin, who confirmed the identity of the prey: termites! Another unique and delightful experience at the Madrona Marsh Preserve!
