Arizona is home to 28 species of bats, more than almost any other state. Bats are the only true flying mammals and are valuable human allies. Worldwide, they are primary predators of vast numbers of insect pests, saving farmers and foresters billions of dollars annually and helping to control insect-spread human diseases.
I love bats. They sleep out of the way in deep dark damp caves, they give us amazing fertilizer, they pollinate millions of plants, eat billions of bugs, and because they know folks think them scary, they are polite enough to do it all on the night shift, silently. Then they sleep upside down, and see by radar just to prove that there is more than one good way to do something. We all would literally be in a world of hurt and disease without bats.
