  • Diet: Their diet primarily consists of insects, including beetles, spiders, and aquatic invertebrates.
  • Reproduction: Breeding season starts in early spring, with females laying masses of 300 to 1300 eggs. The eggs hatch into tadpoles which metamorphose into frogs by summer’s end.
  • Special Characteristics:
    • Their backs and legs are covered in dark black or brown spots, giving them their common name.
    • Oregon Spotted Frogs are known to be relatively sedentary, often staying within a few hundred meters of their home pond throughout their lives.
  • Conservation Status: Listed as “Threatened” under the U.S. Endangered Species Act. The primary threats to their populations include habitat loss, predation, and disease.

Historical Significance

The Oregon spotted frog has a storied history in the Pacific Northwest:

  • Cultural Importance: Indigenous tribes in the region have long revered the frog as a symbol of fertility and transformation. It frequently features in tribal folklore and rituals.
  • Ecological Role: As a keystone species, the frog plays a vital role in maintaining the health of wetland ecosystems. They help control insect populations and serve as a food source for various predators.
