Wood Frog - Rana sylvatica


The coloration of this 2- to 3-inch (5- to 7.6-cm) frog is an adaptation for blending with the leaves on the forest floor. Dorsal coloration ranges from gray, to pinkish, to nearly rusty orange. A brown patch extends from the eye to the tympanum. A dorsolateral ridge extends from the tympanum to the pelvis.



Among the first frogs to breed in the spring. They lay their egg masses attached to submerged twigs in vernal pools in woodlands. The eggs hatch within a few days. Metamorphosis is relatively fast.






Moist woodlands, usually with oak, beech and maple trees.



Small invertebrates.



Found throughout Connecticut.



Common, though habitat loss and pollution may prove detrimental.
