occurs through the central portion of South America, extending south along the Andes from Colombia through Equador and Peru, east to northeastern Brazil, and further south to northern Argentina.
These bats prefer damp forests. They roost mainly in the tops of trees, under the leaves, but have also been found on lower branches (particularly during stormy weather) and in caves.
White-lined bats have a stout muzzle, fairly large ears, and a well-developed noseleaf and tragus. The calcar is short. The fur is yellowish brown to dark brown on the back, and lighter on the ventral surface. True to their name, they have several white stripes. There are two on each side of the face, one running from the base of the noseleaf to the ear and the other across the cheek below the eye. There is also a white stripe on the animal's back.
In general, these bats can reproduce throughout the year and sometimes become pregnant again while still nursing the offspring from the previous pregnancy. In northeastern Brazil, however, there has been found to be a more restricted pattern of reproductive events. Pregnancies occur only from the early dry season in July through the end of the rainy season in early March, and there is a bimodal distribution of breeding and lactation during this period. Females normally give birth to a single offspring, although twinning is also possible. Gestation lasts approximately 3.5 months.
White-lined bats are social, and can usually be found roosting in small groups. Mothers roost with their pups, and females without young are found with a male and sometimes also with several other females. Males are thought to defend their access to groups of 1 to 15 females from other males. Groups often remain together while foraging as well. Like most other bats, this species is active mainly at night.
White-lined bats eat mainly fruit, but will also consume some insects (especially moths), and nectar from flowers.
White-lined bats disperse the seeds of fruit trees, pollinate some plants, and help control insect pests.
This species was formerly known as Vampyrops lineatus.

animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.

rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground. Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal.
