They emerge from the roost to forage for food in the late evening, and return just before dawn. They hang upside down, with their wings folded closely around their bodies. Egyptian fruit bats, along with other species in the genus "Rousettus", are the only megachiropterid bats to use echolocation, which they accomplish by emitting a series of sharp clicks with their tongues. The clicks are normally slow and constant, but these clicks speed up dramatically when the bats approach an object.
Dwarf dog-faced bat is insectivorous and forages in groups. They generally eat small beetles, termites, winged ants, and moths. Some have been appeared to consume pollen, as well, which is common in insectivorous bats, but this is not confirmed, as the pollen could have been picked up while foraging for insects in flowers. This species is nocturnal, and uses echolocation to hunt for prey. They have been observed to roost near food sources to minimize foraging costs. This species of bat utilizes a polygynous mating system, with males mating with many females in a single breeding season. The breeding season varies region to
