Onychonycteris known species, hence "Onychonycteris" meaning "clawed bat". The specific epithet is a tribute to the fossil prospector and preparator who discovered it, Bonnie Finney. "Onychonycteris finneyi" was the strongest evidence so far in the debate on whether bats developed echolocation before or after they evolved the ability to fly. "O. finneyi" had well-developed wings, and could clearly fly, but lacked the enlarged cochlea of all extant echolocating bats, closer resembling the old world fruit bats which do not echolocate. This indicates that early bats could fly before they could echolocate. However, an independent evaluation of the "Onychonycteris" reference fossil in
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
