Spring Peeper

Spring Peeper – Amphibians and Reptiles of North Carolina
The spring peeper is one of many North Carolina frogs that spends much of its time living in upland habitats. The spring peeper’s most distinctive trait is the dark cross or X-shaped blotch that usually is found on its back. In fact, the species name “crucifer” means “cross bearing.”

The spring peeper is a small, delicate frog reaching no more than 1 inch as an adult. Overall, it is mostly smooth, with slender legs. It is noted for the X mark on its back and small pads on its toes. But more often than not, the X is an imperfect one. The dorsal coloration can vary from gray to brown.
