The Little Brown Bat

Adult bats have an average wingspan of 9 to 11 inches, and a body length of 2 1/2 to 4 inches. They are small! Their fur ranges in colors of dark browns to reddish browns, with lighter-colored, pale tan bellies. Females carry their young for 60 days, before giving birth to a single bat pup each year. Mating season usually begins in early fall, while birthing season starts in May and continues through July.

After 14 days in their mother’s care, bat pups are weaned from milk and taught to fly and hunt for insects. Little Brown bats, like all bats, are nocturnal, which means they are active from dusk until dawn. Generally, this bat species remains in large numbers, with colonies reaching hundreds or even thousands of bats in some regions.

Typically, Little Brown bats roost in hollowed tree cavities, abandoned mines, caves, log piles, and similar private areas. They are a hibernating species, so in winter, they either migrate to winter roosts, or hibernate in caves, rock crevices, storm sewers, and if they can access them, our attics!

As insectivores, Little Brown bats hunt for mosquitos, gnats, moths, crane flies, beetles, mayflies, and other small flying insects. A single bat can consume more than 1,000 flying bugs in just one night! That is excellent pest control, and it’s free!

Big Brown Bats

The Big Brown Bat

The Big Brown bat may look like the Little Brown bat, but they are a different species, and just a tad larger, as the names implies. Adult bats have an average wingspan of 13 to 16 inches, and a body length of 3 1/2 to 5 1/2 inches. They are a little bigger as you can see! The rest of their biology and behaviors are the same, with just slight differences.

Their fur is the same as Little Brown bats, ranging in colors from dark browns to reddish hues and lighter-colored bellies. Gestation periods and breeding are the same for both species, as well. Females carry their young for 60 days, before giving birth to a single bat pup each year.

Mating season usually begins in early fall, while birthing season starts in May and continues through June. After 14 days in their mother’s care, bat pups are weaned from milk and taught to fly and hunt for insects. In contrast to Little Brown bats, Big Brown bats tend to roost in smaller colonies, ranging from as little as 20 bats, up to 500 or more.
