Long-Legged Myotis
Myotis volans
DescriptionThe long-legged myotis looks similar to the little brown myotis but can be distinguished by its well developed calcar and slightly larger body. The body mass can be 6-10 grams and the wingspan is 10-12 inches (25-30 centimeters). These bats typically have fur on the inside of their wings that extends from the body to the elbow and knee.

DistributionThe long-legged myotis covers a wide range distribution. They have been found from southern Alaska down to northern Mexico.
This bat has also been captured frequently over the state of Utah.

Ecology and BehaviorTheir diet consists mainly of moths that they catch on straight path flights. Since they roost in trees, the long-legged myotis inhabit forested areas. They have also been seen roosting in rock crevices and buildings. Hibernation occurs in caves and mines.
Red dots indicate captures prior to 2009 and yellow dots indicate captures after 2009. The yellow line separates the Great Basin ecoregion on the left from the southern Rockies region on the right.

Echolocation Signature
|
The shape of the long-legged myotis' calls can appear to be hooked at high frequencies of 70-80 kHz as the bat starts the call. The range of their calls is similar to other myotis species, 39-44 kHz. The oscillogram (green shapes at the bottom of the sonogram) tend to have a power surge in the middle to right side.
