General Information

Lasiurus cinereus is a large and distinctively marked bat with long narrow wings. Its fur is long and soft, dark brown to black at the base, followed by a broad band of cream color, then a slightly narrower band of mahogany brown, tipped with white. The outer three colors are visible from the surface, giving the fur a hoary appearance. The bat has a distinctive yellowish-brown collar under its chin and yellowish ears edged in black. Dense fur extends to the tip of its tail and just beyond the wrists along the undersides of its wings, with distinctive white patches on the shoulders and wrists. Its forearm measures 50-57 mm and this bat weighs 20-38 g. It can be distinguished from all others by its coloration and size.
