 Although flying insects are the main food source of the long-legged bat, these bats have also been known to supplement their diet with animal blood, but not with fruit.Due to the prominence of its posterior extremities and large feet, researchers have suggested aquatic hunting in these bats similar to "Noctilo" fish-eating bats, but this has yet to be proven.The most commonly observed foraging strategy of "M. macrophyllum" is gleaning, in which a bat will hover over a body of water and pick up insects on the surface using its enlarged feet and long hind limbs.
