More Information:

Physical Characteristics

Upper side with smooth (unkeeled) scales, typically a uniform grass green (bluish after death, including in preservative); belly pure white; anal scale divided; nostril centered in single scale; maximum total length in our region at least 62 cm (24.4 inches). 

Juvenile

Upper side olive gray. 

Hatchling

Upper side gray or brown.

Range

Patchy distribution around the margins of the mountains, generally at elevations of 5,500-9,000 feet. Locally fairly common but somewhat hard to find.

Habitat

Lush growths of herbaceous and shrubby vegetation along mountain and foothill streams and meadow habitats adjacent to riparian vegetation. In western Colorado, may be common in mountain shrublands far from water. Usually on the ground, sometimes climbs into low vegetation. Takes shelter in burrows, beneath rocks or wood, or in rotting logs.

Diet

Insects, spiders, and other invertebrates are the main foods.

Reproduction

​Limited information suggests that females produce a clutch of eggs in July. Multiple females may lay eggs in a single site. Hatchlings emerge in late August and September. Activity occurs in daytime and at dusk.
