A wide range of animals and insects live in Texas. It is the home to 65 species of mammals, 213 species of reptiles and amphibians, and the greatest diversity of bird life in the United States—590 native species in all. At least 12 species have been introduced and now reproduce freely in Texas.
Texas plays host to several species of wasps, including an abundance of Polistes exclamans, and is an important ground for the study of Polistes annularis.
