The hoary bat (Lasiurus cinereus) and the silver-haired bat (Lasionycteris noctivagans) are caveless, summer-only bats and also our only other chiropteran residents that have striking coloration.
Size is relative. To my cat, I am rather large; to my dog, not so much. A blade of grass to an ant is like a small tree to you and me. So when I tell you that our largest bat, the hoary bat, has a wingspan of 15 to 16 inches and a body over six inches in length, you must realize that this is a significant bat, even if it weighs only about an ounce.
