The Little Brown Bat (Myotis lucifugus) is a small species of bat commonly found in North America. It has a wingspan of about 8 to 10 inches and weighs around 5 to 14 grams. This bat is known for its brown fur, which can vary in shade, and its large ears. Little Brown Bats are nocturnal and primarily feed on insects, making them important for pest control. These bats typically roost in caves, tree hollows, or buildings, often in large colonies. They hibernate during the winter months, seeking out cool, dark places to conserve energy. Unfortunately, the Little Brown Bat population has declined significantly due to white-nose syndrome, a fungal disease that affects hibernating bats.
