Northern Long-Eared Myotis, Myotis septentrionalis

The northern long-eared myotis, a member of the vesper bat family, is primarily found in the coniferous forests in Newfoundland to the Yukon and in the southeastern United States, in places like Florida. Some of these bats have been found as far east as Texas and British Columbia. They can weigh between.2 and .4 grams, making it a very small bat. The average body length of the northern long-eared myotis is 3.3 inches.

Female northern long-eared myotis bats will usually give birth to only one pup a year. They have been known to form nursery colonies of up to sixty bats. Unlike other myotis bats, they tend to roost individually. These bats will move into caves when it is cold, but little is known about their migrating and hibernation patterns.

The northern long-eared myotis has very long ears. They are yellow on their bellies and are brownish in color on their sides and back. Their small size allows them to maneuver in their environment, and it also helps them to catch food better. These bats will mainly eat moths, but are known to eat other insects. It will sometimes use a special technique to eat, called gleaning, in which it picks moths off surfaces, instead of catching them in flight. The northern long-eared myotis bat has a conservation status of least concern.
