| This close cousin to the eastern red bat (Lasiurus borealis) is genetically distinct. These bats are found along the west coast and southwestern US and into Mexico where thought to hibernate in the winter. Lasiurine bats are solitary creatures that roost in broad leaved trees, especially cottonwoods and willows in the foothills and lower mountains of the southwest and in the fruit and nut orchards of the west, where they resemble dried leaves when they are curled up and asleep. They are often found near streams. Their preferred diet is moths - street lamps are the ideal cafeteria for these tasty morsels.
