I don't have enough information in the provided context to write an accurate overview. The context only states that vampire bats are "a subfamily of mammals," which is insufficient to explain what they are or why they matter in plain language.

Vampire bats, members of the subfamily Desmodontinae, are leaf-nosed bats currently found in Central and South America. Their food source is the blood of other animals, a dietary trait called hematophagy. Three extant bat species feed solely on blood: the common vampire bat (Desmodus rotundus), the hairy-legged vampire bat (Diphylla ecaudata), and the white-winged vampire bat (Diaemus youngi). Two extinct species of the genus Desmodus have been found in North America.
