Other
The only North American Frog found north of the arctic Circle. Primarily diurnal. In the colder parts of its range, the Wood Frog is an explosive breeder. Swarms of pairs lay fertilized eggs within 1 or 2 days, then disappear into the surrounding country. It may venture far from water during summer, and hibernates in forest debris during winter.
