Keep Herp Calendar free

Hi, I'm Nick. I built Herp Calendar on my own and I keep it free, with no ads. If it has helped you find a herp this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.

Common Side-blotched Lizard

Uta stansburiana

Look, don't take. Many states regulate collecting reptiles and amphibians. Photograph it, log it on iNaturalist and leave it where you found it.

Description

The common side-blotched lizard (Uta stansburiana) is a species of side-blotched lizard in the family Phrynosomatidae. Males can grow up to 60mm (2.4 inches) from snout to vent, while females are typically a little smaller.Wikipedia ↗

Habitat

The species is native to dry regions of the western United States and northern Mexico. The three morphs compete against each other following a pattern of rock paper scissors, where one morph has advantages over another but is outcompeted by the third.Wikipedia ↗

When it's active

Female side-blotched lizards lay clutches with an average of 5.1 eggs and a maximum of 9 eggs in a single clutch. Smaller clutch sizes, often associated with yellow-throated females, have an increased frequency of eggs bursting upon being laid or egg binding, suggesting an upper physiological limit to how much a female can invest in each individual egg she lays.Wikipedia ↗
