There are two species of anoles found in Texas, the Green Anole and the Brown Anole (also known as the Cuban Anole or Anolis sagrei). The Brown Anole came to the United States via Key West in the 1900s and since then have established a presence in much of the Southern United States. The Brown Anole is crowding out the Green Anole in many habitats, but some believe this is causing the Green Anole to move higher up in plants and trees leaving the ground and lower plants areas for the Brown.
Anoles, both Brown and Green, eat live insects and have a life span of 18 to 36 months on average. They grow up to eight inches in length.
Update: According to several observers on iNaturalist the lizard in the picture is actually a Green Anole, which can sometimes be brown in color.
