The northern hoary bat, L. cinereus, is a solitary, foliage roosting, insectivorous bat that, in contrast to the Hawaiian hoary bat, Lasiurus semotus, undergoes large-scale annual migrations in gyres across large reaches of North America, likely in response to seasonal availability in food (Cryan 2003; Hayes et al. Hoary bat, (Lasiurus cinereus), migratory North American bat found in wooded areas from Canada to Mexico. Mating is followed by delayed fertilization, a process in which the sperm is stored in the female reproductive tract all winter and doesn't fertilize the egg until the next spring.
