The bat is often portrayed as a vampire, a taxonomic monstrosity, and a source of the worst evils. Whenever pandemics occur, such as the one currently spread by SARS-CoV-2, this animal is quickly identified as a "reservoir of emerging pathogens" and is among the first to be blamed. Yet many human groups live in daily contact with multiple bat species and eat their flesh, which they praise for its medicinal benefits. Such groups see the bat as a "companion species" with which they cohabit and establish cooperative relationships. In this paper, we use recently gathered ethnographic data from Southeast Asia to show how humans imagine bats and enter into relationships with them. By blurring the boundaries between nature and society, this animal has made itself an appropriate subject of study for contemporary anthropology.
