They are found in the eastern part of southern Canada and the U.S. to the Rocky Mountains in some places.
They live in wet woodlands near water and swamps.
They reach about 2 inches long. They are usually gray with darker spotted patterns. They have a light-colored spot with a dark edge under each eye. They blend in very well (camouflage) and are hard to see. They have sticky toe pads to cling to trees.
They have a trilling song. They are active at night (nocturnal). They can survive being frozen in winter.
They eat insects and tadpoles.
They are eaten as tadpoles by other pond animals and birds.
They sit in trees near the water and call for a mate. The females lay their eggs in shallow water attached to rocks or plants to keep them from floating away. The tadpoles hatch, breathing with gills and will, over time, grow into the adult frogs.
Species: H. versicolor
