A little brown bat eats roughly 4 to 8 grams of insects a night, which puts a real dent in local insect populations. Bats are the only mammals that truly fly, and with more than 1,200 species identified worldwide, some climb to altitudes of roughly two miles. Even so, the 2023 North American State of the Bats Report found that 52% of the continent's 154 bat species are at risk of severe population decline within 15 years, and 10 U.S. species are federally listed as endangered, with one more listed as threatened.

Bats are the only mammals that truly fly, and that alone has kept them in folklore, films, and pop culture for centuries. Here are some of the most interesting bat facts on record, plus a look at how these nocturnal fliers have turned up in movies, songs, and storybooks over the years.

Fascinating Bat Facts

Bats are small, but what they can do is out of proportion to their size. A little brown bat can put away roughly 4 to 8 grams of insects in a single night, which makes it one of nature's better pest-control agents. Scientists have catalogued more than 1,200 distinct bat species, and depending on the type, their menu ranges from insects to frogs and small rodents. Some species climb to altitudes of roughly two miles, and bats are found worldwide.

Bats are also surprisingly meticulous groomers. They spend a large chunk of their day cleaning their fur, much like a cat would. Reproduction is where they lag, though: pound for pound, bats have one of the slowest breeding rates of any mammal.

A baby bat is officially called a pup, usually born and raised in a roost tucked inside a cave, hollow tree, mine shaft, or barn rafters. The conservation numbers are grim: the 2023 North American State of the Bats Report found that 52% of the continent's 154 bat species are at risk of severe population decline within 15 years, and 10 U.S. species are federally listed as endangered, with one more listed as threatened.

  • A little brown bat eats roughly 4 to 8 grams of insects a night; the widely repeated hourly mosquito figure comes from a 1960 lab experiment and overstates what bats do in the wild, where they prefer moths and beetles to mosquitoes.
  • Over 1,200 bat species have been identified worldwide.
  • Bats spend much of their time grooming themselves.
  • The 2023 North American State of the Bats Report found that 52% of the continent's 154 bat species are at risk of severe population decline within 15 years, and 10 U.S. species are federally listed as endangered, with one more listed as threatened.
  • Bats reproduce more slowly than almost any other mammal relative to their size.
  • Their diet can include insects, frogs, and small rodents.
  • Certain bats fly at altitudes of about two miles.
  • Bats are found worldwide.
  • A baby bat is called a pup.
  • Common roosting spots include caves, trees, mines, and barns.
  • Scientifically, bats fall under Kingdom Animalia, Phylum Chordata, Class Mammalia, and Order Chiroptera.

Bats in Movies, TV & Music

Bats have haunted and delighted the screen for decades. Vampire-tinged thrillers like Hammer's The Kiss of the Vampire (1963), which ends with a swarm of bats descending on the vampire cult, and The Abominable Dr. Phibes (1971) leaned into their spooky reputation, while the horror flick Bats (1999) and the drama The Lost Weekend (1945) both put winged creatures front and center.

On the gentler end, the animated tale Stellaluna (2004) explored the animal itself, while the 2005 CBS television horror movie Vampire Bats set Lucy Lawless against a swarm of mutated bats in Louisiana. 1989's Batman turned the creature into a full-blown superhero icon. Musicians have been just as taken with bats β€” Meat Loaf's anthem "Bat Out of Hell," Avenged Sevenfold's "Bat Country," Prince's "Batdance," and Deep Purple's "Rat Bat Blue" all borrowed the bat's dark reputation for their titles.

Famous Bats

A few bat characters keep turning up across pop culture. Grandpa Munster, the shape-shifting patriarch from TV's The Munsters, could transform into a bat on command. Batman, star of comics and films for decades, borrowed the animal's name and silhouette to build his entire crime-fighting persona.

In children's literature, Stellaluna tells the story of a bat raised among birds, and Bartok, the wisecracking sidekick from Anastasia, brought comic relief to the big screen.
