The hoary bat is one of the most distinctive bats in Utah. The body weight varies between 25-30 grams. Typical wingspan is 13-16 inches (34-40 cm).
The pelage coloration is a mix between dark brown and gray with white tips. This gives the fur a frosted appearance. Their wrists and shoulders have white fur patches and the neck has a yellow fur patch. The ears are very short and furry.
The hoary bat is the most widespread bat in the Americas. Hoary bats have been found all over mid to southern Canada, throughout the United States, in Central America, and as far south as Chile and Argentina in South America. Hoary bats are also indigenous to Hawaii.
Ecology and Behavior
Hoary bats prefer to roost individually in trees. The diet of these bats consists mainly of moths but they will also consume beetles and grasshoppers. The hoary bat has also been reported to be carnivorous (smaller bats).
Males and females segregate during the summer. Females can give birth to one to four offspring, with the average of two.
