Vesps

Vesps appeared in 2019 Netflix movie called The Silence. Vesps are a bunch of rare prehistoric blind bats living in a subterranean cavern that's about 1,000 ft below the surface of Pennsylvania’s Appalachian Trail.

Since the Vesps are blind they relied on they're sense of hearing, because they'red attracted to loud noises. So if its a person that made some or in a close proximity of a creature (i.e. rattlesnake) it will swoop down and starts attacking that person with its teeth and claws until the person is dead, however if its an object say-like a wood chipper the vesps will end up dead.
