SVL -4.5 cm
Found under a rock around 530 pm. Temps in the 60s, no clouds. Male
I found this lizard at 4:00pm in a pit fall trap I made that cuts off two halves of a junkyard. The junkyard is bordered by grassland on one side and a pecan grove on the other.

I saw this lizard on a railroad tie on a limestone outcrop by a wash where Lake Travis used to intrude at about 11:30am. There was full cloud cover and it felt to be about 70°F. Wind speed was about 10mph.

It has been used as a model system in lizard life-history studies and populations produce...
