With picky eating, bats avoid poison prey. A series of experiments conducted by scientists at the Smithsonian Tropical Research Institute in Panama have revealed that frog-eating fringe-lipped bats (Trachops cirrhosus) are, by necessity, much more discerning diners than previously known.

Adult free-tailed bats are capable of eating 3000 to 5000 insects a night, including flying termites, flying ants, moths, mosquitoes and fruit flies. They are also known as "Billion-dollar Bats" because of the amount of pest control they provide to agriculture.
