The lesser long-nosed bat has brown to gray fur and an unusual split in its tail membrane. Inhabiting desert areas, this species forms large aggregations in cave or mine roosts. Lesser long-nosed bats may migrate over 1,000 miles between their winter and summer ranges! A nectivore, the species is a frequent pollinator of agave and columnar cacti and may opportunistically feed at hummingbird feeders. Mothers give birth to one pup a year. This bat can survive to over 20 years in age in the wild.
