Pine Barrens tree frogs are pale green, with a longitudinal black stripe on each side of the body that forms a facial mask. This stripe is often bordered by a white or lavender line. The forearms are green and white on the underside and the hands and feet are pale cream in color. The face is shorter than other North American tree frogs. It is easily distinguished from other similar tree frogs by its size and the longitudinal stripes described above.
 

Tree frogs can be somewhat long-lived in captivity, but it is difficult to assess their age in the wild. Records show Pine Barrens tree frogs in captivity can live up to 5 years. 
 

Pine Barrens tree frogs are both terrestrial and arboreal. They are nocturnal animals that sometimes like to bask in the sun.  When doing so, the frogs tuck in their hands and legs, and secrete a protective coating to prevent the air and direct sun from drying them out.

Pine Barrens tree frogs form loud choruses in early successional shrub bogs, seeps, and sphagnum ponds where you can hear their loud calls. A series of rasping wha-wha-wha-wha’s are repeated at a fast rate, usually after rain during warm summer nights.  Females approach the group of calling males and usually choose a partner.  Once chosen, the male will mount the female in a nuptial froggy embrace known as amplexus.  The female will then take the male to a secluded area of the pond where she will lay up to 1,000 eggs.  Fertilization, as in most frogs, is external. These breeding sites are very acidic and nutrient-poor, and potentially serve to exclude ecological competition from other amphibians living in the Pine Barrens.
