Western Small-Footed Myotis
The Western small-footed bat is one of the smallest myotis species. It weighs between 4 - 6 grams and its wings measure 8-10 inches (21-25 cm). The face and ears are typically a dark brown that contrast with the light brown to yellowish brown of its pelage. The pelage on the belly is typically lighter than the pelage on its back. This species is easily confused with the California myotis. The defining characteristics are a gently sloping forehead, broader nose, and a tail that extends 4mm past the end of the membrane.
This species can be found in southern Canada and throughout the United States.
In Utah, this species is routinely captured statewide.
