  • Often Not Confused with other Species

IDENTIFICATION

 

Size:                  A medium sized frog measuring 1.5 to 2.5 inches in

                           length.

 

Color:                The dorsum is light tan to dark brown in color with two

                           dark brownish black mask-like markings behind the

                           eyes. The venter is white.  The thighs are sometimes

                           colored yellow.               

 

Behavior:         When encountered wood frogs may freeze in place

                           crouching low to the ground relying on their cryptic

                           coloration to conceal their presence against the

                           background leaf litter.  If concealment does not work

                           they are quick to flee, seeking shelter in nearby

                           vegetation or under the cover of leaf litter, rocks or logs.             

Habitat:            Wood frogs occur in a variety of forested habitats across

                          the state.  They require seasonal wetlands for egg

                          deposition and larval development; vernal pools are

                          preferred.
