The legs have bars on them. The plain belly is a slightly lighter shade of the ground color. There are no subspecies of Pseudacris crucifer recognized. Range Spring peepers are found in woodlands in eastern Iowa.

Habitat Spring peepers are a woodland-woodland edge species. They are not found in open areas or large bodies of water. Smaller wetlands, even some that may dry up later in summer are used for breeding by spring peepers. Habits Spring peepers are heard earlier in spring not long after ice melts on the wetlands. Their normal breeding season lasts from April through May.
