Underwood's mastiff bats have been seen roosting in hollow trees and under palm fronds, and have been captured in mist nets over pools of water in the desert, but little is known about their daytime roosting habits or about their winter range. This bat's large mouth and strong jaws suggest that it may include hard insects such as beetles and grasshoppers in its diet, and its long, narrow wings and the bones and muscles of its shoulders suggest that it may be able to fly all night, without resting, as it hunts. Learn more about the Eumops underwoodi, more commonly known as an Underwood's Mastiff Bat, in this easy-to-read species overview by the Smithsonian's National Museum of Natural History.
