Western Long-Eared Myotis
The Western long-eared myotis is easy to distinguish because it has the longest ears of the myotis species. The weight of this species ranges 5-8 grams and their wingspan is 10-12 inches (25-30 cm). The pelage is dull and pale brown to yellow-brown.
Western long-eared myotis is found throughout the south-central portions of the western Providences of Canada and the western United States.
The Western long-eared myotis has been captured in many locations in Utah excluding arid/desert regions.
Ecology and Behavior
The Western long-eared myotis relies on sound when foraging in dense vegetation. The bat listens for insect sounds, verifies the position of its prey with echolocation, then gleans the prey from the leaves or bark where they rest.
The diet of the Western long-eared myotis includes beetles, moths, flies, and lacewings.
