Lasiurus borealis, commonly known as the eastern red bat, is a species of bat found primarily in North America. It is characterized by its reddish-brown fur, which helps it blend into its surroundings, particularly in trees. This bat is medium-sized, with a wingspan of about 30 to 35 centimeters, and is known for its distinctive long ears and large eyes. Eastern red bats are typically solitary and roost in trees or shrubs during the day. They are insectivorous, feeding on a variety of insects, including moths and beetles, primarily during the night. Their habitat includes forests, urban areas, and open fields, making them adaptable to different environments.
