Lasiurus cinereus, commonly known as the hoary bat, is a medium-sized bat found across North America. It has a distinctive fur that is grayish-brown with white tips, giving it a frosted appearance. This species typically roosts in trees and is known for its long, pointed wings, which allow for agile flight. The hoary bat primarily feeds on insects, including moths and beetles, and is most active during the evening and night. It migrates seasonally, traveling long distances to find suitable habitats. Lasiurus cinereus plays a vital role in controlling insect populations in its ecosystem.
