Colorado Checkered Whiptail
Look first for bold cream stripes and checker marks on a long, fast whiptail, then confirm it in open piñon-juniper, shrubland, and canyon terrain in southeastern colorado. Those two clues make Colorado Checkered Whiptail much easier to identify responsibly in Colorado.

Colorado checkered whiptails are all female and reproduce through parthenogenesis, producing young without fertilization. Their patterned bodies and extraordinary speed suit warm, open ground where they forage actively for insects.
The natural range is concentrated in southeastern Colorado, with introduced populations elsewhere. Watch from trails during warm morning activity, distinguish the lizard from other whiptails using several pattern features, and never chase or handle an animal for a closer photograph.

- The long tail and rapid stop-start foraging fit a whiptail better than a stockier fence lizard.
- Protect the site
- Do not move rocks, collect an individual, or disclose a sensitive colony location.
