Size:
  • ¾ inch to 1 3/8 inches from snout to vent

  • Record: 1 ½ inches


  • Appearance:
  • Difficult to distinguish between the Upland and New Jersey Chorus Frogs based on appearance so they are usually differentiated by geographic range in Maryland

  • Generally brown or gray but can be extremely variable.

  • There is a light line along the upper lip

  • Usually a dark triangle, pointing backward, between the eyes on the back of the head

  • Usually 3 dark stripes from the snout to the tailbone, two passing through the eyes, and one down the middle of the back. These lines may be broken or spotty.

  • These lines tend to be slightly thicker on New Jersey Chorus frogs.

  • The underside is off-white with occasional spots.


  • Habitats:
  • Wet areas that include slow moving or non-moving water, such as grassy floodplains and wet woods, vernal pools, forested swamps and wet meadows.

  • May be found developed areas, dry fields and urban environments during non-breeding season, as long as there is water nearby.

  • In Maryland, found west of the Susquehanna River to the eastern edge of the Allegheny Plateau in Allegany County.


  • How to Find:
  • From February through April, listen for its call, the slow ascending scale of the sound of a finger running up a comb, Creeeeeeeeeek
