Pickerel Frog

Lithobates palustris

Identification

The Pickerel Frog looks somewhat similar to the Northern Leopard Frog; however the Pickerel Frog is always brown (leopard frogs can be green or brown), spots on its back are somewhat rectangular, outlined in black, and tend to be organized in two rows.  Sometimes the spots fuse to form bands.  Pickerel Frogs measure 1½-3 inches long. They have prominent dorsolateral ridges, a white chest and belly, but a yellow “waistcoat” and yellow down the insides of its legs.  Their yellow and brown eggs form a dense mass.

Pickerel Frogs call in Vermont from mid-April to mid-June, most commonly in the latter half of May. The Pickerel Frog’s call is described as a short snore.
