Most of the bats in the world; all bats except fruit bats; insectivorous bats.

Most microbats feed on insects. Some of the larger species hunt birds, lizards, frogs or even fish. Microbats that feed on the blood of large mammals (vampire bats) exist in South America.

1. Microbats use echolocation, whereas megabats do not.
2. Microbats lack the claw at the second toe of the forelimb.
3. The ears of microbats don't form a closed ring, but the edges are separated from each other at the base of the ear.
4. Microbats lack the underfur; they have only guard hairs or are naked.
