Wagner's mastiff bat is considered endangered by the state of Florida, where habitat destruction and the use of pesticides may be contributing to its decline. It is a medium-sized bat with long, narrow wings. These bats leave their day roosts after dark and fly high, covering long distances quickly as they feed on insects. Eumops glaucinus is a freetailed bat. Like other bats in the family Molossidae, its tail extends beyond the tail membrane, or uropatagium (the skin that stretches between the back legs).
