Male and female Blanchard's cricket frogs look alike, but females are usually larger. Males have a dark vocal sac on their throats that they inflate to help make their mating call. Back color is variable, but is usually brown, gray, olive, or tan, sometimes with a green or reddish stripe running down the middle. Their moist skin has raised reddish spots, or warts. There is a dark triangle or V-shaped spot between their eyes, often rust or lime green in color.
Bellies are white and each thigh has dark, ragged crossbars that create a somewhat netlike pattern.
Distribution Historically, Blanchard's cricket frogs were found from Southwestern Ontario, Michigan, and Ohio west to Nebraska and south to include most of Texas. Small populations extend into eastern Colorado and New Mexico. Today, this species has almost disappeared from much of the Northern portion of its range, including Ontario, most of Michigan, Minnesota, Wisconsin, Illinois, and Iowa. In Wisconsin, the historical range of the Blanchard's cricket frog was limited to the southern half of the state. A map outlining Pre-1977 and 1997 to Present Distribution is available.
