| Bats in the family Molossidae have long, narrow wings and are fast fliers. They cannot maneuver as well as bats with shorter, broader wings, and therefore they tend to fly above dense vegetation and catch insects in flight, leaving the prey within the canopy to other bats. Aztec Mastiff Bats are found at mid- to high elevations, often roosting in hollow trees or houses. Colonies of as many as 300 may roost under a corrugated roof, and are sometimes seen emerging one by one at sunset. They feed mostly on beetles.
