What Do Bats Eat?

Bats feed primarily on flying insects, including mosquitoes, beetles, crickets, moths, and chinch bugs.

A little brown bat—a very aptly-named creature with a body smaller than your thumb—can eat its entire body weight in insects in a single night.

When you account for all of the bats in North America, that’s a lot of insects. In fact, it has been estimated that the reduction of bat populations in the Northeastern United States means there are up to 1,320 more metric tons of insects every year.

Some bats eat fruit, as well as pollen. They are actually very useful pollinators, leaving their mark as they fly from tree to tree in search of food.

Where Do Bats Live?

Bats seek refuge in dark and quiet locations that are protected from the elements. These include caves, bridges, mines, old buildings, and trees.

Little brown bats often seek solace in tree cavities. Hoary bats seek the protection of trees with thick foliage. The Indiana bat roosts in cave roofs, often in tight clusters.

What is the Largest Bat in North America?

The western mastiff bat, also known as the greater mastiff bat, is one of the largest bats in the United States. The hoary bat also ranks highly on that list.

What Families of Bats are Found in North America?

To What Family Do Bats Belong?

Bats belong to the order Chiroptera, which comes from the ancient Greek words meaning “hand” and “wing”. In Old English, the bat was known as a “flittermouse”, and it had a similar name in old German and Swedish. This name essentially means “fluttering mouse”.

Interestingly, similar words are still used in Swedish (fladdermus), Norwegian (flaggermus), Danish (flagermus), and German (fledermaus). And while we borrowed the order name from the Greeks, they use “νυχτεριδα” which comes from “nocturnal”.

Many North American species of bats are in the “myotis” order, which comes to us from Latin (via Greek) and means “Mouse Ear”. It is a reference to the fact that their ears are longer than they are wide.

Big Brown Bats vs Little Brown Bats

Little brown bats and big brown bats are known as “house bats”. They can be found hiding out in buildings and you may stumble across them if you’re venturing into attic spaces or basements.

Size is the main difference between the two, as the name suggests. Big brown bats are nearly twice the size of little brown bats.

Big brown bats also have broader noses and silkier coats.
