Little Brown Bats Diet

Little brown bats are insectivores, eating moths, wasps, beetles, gnats, mosquitoes, midges and mayflies, among others. Since many of their preferred meals are insects with an aquatic life stage, such as mosquitoes, they prefer to roost near water. They echolocate to find their prey. Often they will catch larger prey with a wingtip, transfer it to a cup formed by their tail, then eat it - smaller prey are usually just caught in the mouth. They often use the same routes over and over again every night, flying 3-6 meters high above water or among trees. An adult can sometimes fill its stomach in 15 minutes; young have more difficulty. If they do not catch any food, they will enter a torpor similar to hibernation that day, awakening at night to hunt again.

Little Brown Bats

Little Brown Bats:

In summer the little brown bat inhabits trees, bat houses, and buildings, usually choosing a hot attic, where nursery colonies of hundreds and even thousands form. Less frequently colonies form beneath tar paper, siding, shingles, or other similar sheltered spots,. In the west colonies have been found beneath bridges and in caves. Single males have been found in attics, behind shutters under bark, in rock crevices, behind siding and under shingles. Groups of males occasionally occur in caves.


In a summer colony the bats remain alert on warm days. In any large group a few are usually active, crawling about over the others and bickering. A colony can be heard as far away as 100 feet. Toward evening the bats become more active until a constant squeaking can be heard as they gather about the exits. They begin to emerge at late dusk. When there is water nearby, most of the bats head at once for the water where they begin feeding a few feet above the surface as they continue to disperse.
