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. Hoary bats are primarily nocturnal and feed on insects, including moths and beetles. They are migratory, often traveling long distances between summer and winter habitats. Their population is affected by habitat loss and climate change, making conservation efforts important for their survival.
