Field Guide

American toads are well-known and occur statewide. Missouri has two subspecies: the eastern American toad in the northern half, and the dwarf American toad in the southern half.

The voices of spring peepers are a true announcement that winter is ending. These small, slender frogs can be several overall colors, but seeing an X on the back is a good way to ensure your identification.

The eastern spadefoot is a stout, toadlike amphibian with large, protruding eyes, vertically oval pupils, short legs, and large feet. In Missouri, it occurs in eastern counties along the Mississippi River and in the Bootheel.

Unlike other true toads in Missouri, the Great Plains toad has a raised hump between the eyes on the snout. Look for it along the Missouri River floodplain, from the Iowa border to about Hermann.

Fowler's toad is the common toad of gravel and sand bars along our many Ozark streams and rivers. It is also the most common toad in the Bootheel lowlands.

The Rocky Mountain toad has a number of irregular dark brown or black spots on the back and a white belly. It occurs in the Missouri River floodplain, mostly from the central to the far northwestern parts of the state.

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.

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.”

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.
