The breeding period lasts from early spring to June, depending on the region. Northern Spring Peepers begin breeding in the first year after they have hatched. They then undergo metamorphosis, in which they transform into small frogs and begin their life on land.

Because they breed in permanent or temporary water, they need to have pools in their habitat. Although they are good climbers, Northern Spring Peepers seem to prefer to be on the ground or burrowed into the soil. These frogs are found in marshy woods, non-wooded lowlands, and near ponds and swamps. Their cousins, Southern Spring Peepers, inhabit the southern parts of Georgia and northern Florida. In the United States they are restricted to east of the Mississippi river. They can be found from southeastern Canada, in Ontario and Quebec, throughout the eastern United States as far south as northern Georgia. Northern Spring Peepers are only native to the Nearctic region. Average basal metabolic rate 0.00105 W AnAge.This flap can become much darker than normal during breeding season when they are calling the most. Males also often have a flap beneath their throats where their vocal pouches are.

Females tend to be slightly larger and lighter in color. Northern Spring Peepers have slightly webbed feet and noticeable disks on their fingers and toes. Their coloration makes them very difficult to see on the tree bark and leaf litter where they are normally found. Their bellies are cream or white, and they are marked by a dark cross on their backs and dark bands on their legs. Like many frogs, their color can vary with temperature and other conditions of their surroundings. These frogs range in color from shades of brown to gray or olive, and occasionally may be yellow or reddish. The Northern Spring Peeper is a frog that varies in size from 19 to 35 mm at maturity.
