Pickerel Frog (Lithobates palustris), a species of Special Concern in Wisconsin, has a rather complex habitat range as it prefers to overwinter in cold water streams, seepage pools, or spring holes, often taking advantage of water cress for cover. It moves to warmer water ponds to breed and lay eggs from April through mid-June. Adults spend most of the active season foraging on land in riparian habitats along streams and rivers. This species is active from late-March to early-November but can remain semi-active in winter under water. Larvae metamorphose from mid-July to mid-August.
