Little Brown Bat
(Myotis lucifugus)

They are found in a large area that extends from Central America, the United States, Canada, and even as far north as into Alaska. They are shades of brown, which where they get their name from and reach a size of no longer than 4 inches. Their wings can grow to reach a wingspan up to 11 inches and reach weights of around 10 to 14 grams. There is some evidence that proves that the females of the species are larger than the males.
Like most bats, little browns are insectivores that mate in the fall, but the females do not ovulate until springtime. The females give birth to a single pup after a gestation period of 50 to 60 days. These pups are fully independent a month after birth.
