The little grass frog is the smallest frog in North America – adults are only about half an inch long. As their name suggests, these frogs spend their lives in and around shallow grassy ponds and marshes. Because they are so small, these frogs are very difficult to find. They usually perch on grass stems just above the water and align their dark body stripe with the grass. In Florida, Little Grass Frog’s high-pitched chirp can be heard in most months of the year.
