Lasirus cinereus semotus (Hawaiian Hoary Bat)

The Hawaiian Hoary Bat, known as ‘ope‘ape‘a in Hawai'i, has a heavy fur coat that is brown and gray, and ears tinged with white, giving it a frosted or "hoary" look. It is believed to be related to the North American hoary bat and it is the only native land mammal of Hawai‘i. ‘Ope‘ape‘a populations are believed to be threatened by habitat loss, pesticides, predation, and roost disturbance. Its decline may be primarily due to the reduction of tree cover in historic times
