Hoary Bats are found from northern Canada all the way to Guatemala, and also in South America and Hawaii. They are solitary and roost in trees. Their frosted, or hoary, look comes from a tinge of white over their grayish-brown fur. Their flight is distinctively fast and direct and can be used as an identifying trait. Hoary Bats eat moths, beetles, grasshoppers, wasps, and dragonflies.
