Sceloporus sp.

Post by kschnei1 » April 15th, 2016, 5:41 pm

Hi all,

I found a number of lizards up on fence posts recently in Colusa County - here is a photograph of one of them on iNat:

Although I assumed they were S. occidentalis, my photographs seemed to show a rust-colored axilla and a dark band in front of the forelimb, suggesting S. graciosus? I'm confused - any tips on separating these two species from photos would be appreciated!

Thanks,
Ken

occidentalis.

The yellow on the hind legs is a dead giveaway.

Also the fact that the only Scelop in the valley or foothills is the Northwestern Fence Lizard... :)

S. graciosus has white on the back of it's legs, as opposed to yellow (as Owen pointed out) in occidentalis... easy tell... even when running away... :crazyeyes:
