Lasiurus

Lasiurus is the genus comprising hairy-tailed bats. The generic name Lasiurus is derived from the Greek lasios (hairy) and oura (tail). It contains some of the most attractive bats (Chiroptera) in the whole continent of North America, including such species as the eastern red bat, L. borealis, and the hoary bat, L. cinereus. They are very robust and long-winged, with fast and strong flight; several species fly during parts of the day, especially when migrating south in autumn. The hoary bat and red bat will often fly in daylight during winter.
