Big Free-Tailed Bat
The big free-tailed bat is the biggest bat that can be found in Utah. Their wings span 17-18 inches (42-46 cm) and they weigh between 25-30 grams. They can be distinguished from the Brazilian free-tailed bats by their bicolored hairs, which are white near the body. They have large, broad ears and their upper lips are wrinkled.
These bats are found in the southwestern United States from southern Nevada, southern Utah, and southern Colorado down into central Mexico.
These bats have been captured mostly in southern Utah.
Ecology and Behavior
Since these bats are so large, they prefer to fly and forage in open areas. They usually roost in high cliff faces but have been known to use buildings.
They prefer to eat larger sized moths but will also eat flying ants, stinkbugs, and crickets.
