The great striped- faced bat ( Vampyrodes caraccioli ) is the only species of the genus Vampyrodes in the subfamily of fruit vampires . It occurs in Central and South America .
features
With a head-trunk length of 65 to 77 mm, a forearm length of 45 to 57 mm and a weight of 30 to 40 g, the species is a medium-sized representative of the fruit vampires. One tail is missing. The fur has a gray-brown to cinnamon-brown color on the top, while the underside is always gray-brown. Characteristic are four white stripes on the face from the corners of the mouth to the lower approaches of the ears, or from the nostrils to the upper approaches of the ears. There is also a white eel line on the front part of the back. In contrast to the striped fruit vampires ( Platyrrhinus ) there are only two molar teeth. Like the other fruit vampires, the species has a pointed nosepiece .
distribution
The distribution area of the great striped-faced bat extends from southern Mexico through Central America and northern South America to Peru , Bolivia and the Brazilian Amazon . The species is also found in Trinidad and Tobago . It lives mainly in the lowlands and rarely reaches an altitude of more than 1000 meters in mountains. Tropical evergreen forests and neighboring plantations and gardens serve as habitat .
Way of life
These bats live in small harem groups with one male, two to three females and their offspring. Occasionally males only get contact with the group during mating times. The same applies to males who are not yet sexually mature. These can come together in bachelor groups. According to the few studies available, females have two litters per year with one young each. Shortly afterwards, the female mates again.
During the day, the groups rest on heavily leafy branches or twigs of trees and bushes and under palm leaves. They become active around 45 minutes after sunset and usually fly 850 meters before they start looking for food. During the flight, the striped-faced bat usually keeps 3 meters from the ground. She prefers to eat figs , which are complemented with other fruits, nectar and pollen .
status
The species is listed as Least Concern due to its wide distribution area . Deforestation can lead to a local decrease in the population.
