This spadefoot is also known as the Plains Spadefoot, but is listed as the Western Spadefoot in the FrogWatch™ Field Scope database. Notice the four rough stripes on its back and warty skin. There is a raised bone on their head between their eyes called a “boss” which is missing in the Eastern Spadefoot. The Western Spadefoot is smaller than the Eastern and Hurter’s Spadefoot. Their back foot tubercle is more wedge-shaped than their sickle-shaped cousins. He is rarely seen without rain present. Reproductive behavior is similar to the other spadefoots.
Interesting Fact: Spadefoot fossils that are 35 million years old have been found in North America.
The Western Spadefoot is a member of the Pelobatidae (Spadefoot) family and is a Middle Frog (Mesobatrachia).
