Western mastiff bats feed primarily on insects which they catch in flight. These bats rarely utilize night roosts and feed at night, with foraging ranges exceeding 24 km from roost sites, and a long foraging period of 6 to 7 hours. Prey includes relatively small, low-flying, and weak-flying insects. They usually feed from ground to tree-level but may soar to heights of some 60 m in rugged terrain. It is interesting to note that flightless insects, including ants and crickets, comprise part of their diet even though these bats are unable to take off from the ground, requiring that the prey be snatched up as the bat flies by. These prey items are likely to be taken from surfaces such as canyon walls (Cockrum 1960; Texas Tech, 1997; Ahlborn, 2000).
Some insect prey include: moths, crickets, grasshoppers, bees, dragonflies, leafbugs, beetles, true bugs, ants and wasps.
