Field Guide

The plains spadefoot is a stout, toadlike amphibian with large, protruding eyes, vertically oval pupils, short legs, and large feet. There is a raised area between the eyes. It occurs in counties along the Missouri River.

The bright green treefrog hides perfectly among cattail leaves, where it rests until evening. Then it begins hunting for insects. In Missouri, it occurs mostly in the Bootheel.

With its stout body and thick forearms, the rare Illinois chorus frog may at first appear more like a toad. It lives in open, sandy areas that were formerly sand prairie grasslands and wetlands of southeastern Missouri.

Blanchard's cricket frog is a nonclimbing member of the treefrog family. It lacks the adhesive toe pads associated with treefrogs. It occurs statewide. The call is a metallic “gick, gick, gick.”

Prairie racerunners are fast, alert, ground-dwelling lizards. They live in open areas like fields, grasslands, and rocky, south-facing hillsides, including Ozark glades. They are related to the whiptail lizards that live in the western United States.

The eastern gartersnake and red-sided gartersnake are Missouri's most common gartersnakes. The color is variable, but there are normally three yellowish stripes, one down the back and one on each side. There are narrow black bars between the scales along the upper lip.

A medium-sized, striped snake of wet prairies and marshes, the plains gartersnake occurs mainly in Missouri's north-central and northwestern counties, with isolated populations in and west of the St. Louis area.

Prairie ring-necked snakes are easily recognizable by their small size, uniform dark color on the back, bright yellow-orange belly, and distinct yellow ring around the neck. Secretive, but common nearly statewide.

The western slender glass lizard is often called “glass snake” because it is long, slender, and legless, and its tail breaks off easily. But glass lizards are true lizards, with eyelids and ear openings; snakes have neither of these characteristics.

The eastern coachwhip is a long, slender, nonvenomous snake that usually escapes in an explosive burst of speed. In Missouri, it occurs in the Ozark and Ozark border regions.
