The reported lifespan in this species is about five years, but is probably longer. Evening bats are similar to big brown bats, but smaller. In cooler weather, Evening Bats feed only once per night. … Prédation by primates on bats is a rarely reported phenomenon in gen eral; invertebrates are the usual animal prey for most species (Butynski, 1982). An Evening Bat’s best friends are more evening bats and even other species of bats. bat species (Herreid, 1964) and all bats, including those that ... should decrease with colony size as a consequence of predator dilution. They will roost with other species of bats and have strength in numbers when it comes to defense against predators. ... increases with progeny production. Bats are the only flying mammals that are active mostly at night and occur on all continents except Antarctica. Mortality risk should also be lower for species utilizing protected sites, such as caves, as day roosts or as hibernacula. They can be distinguished by their reddish to dark brown fur above and tawny color below. The Evening Bat is a relatively slow and steady flyer that feeds high in the early evening and comes lower after dark. Bats are also an important control on insect populations, and they are preyed upon by many kinds of animals, such as owls and snakes that wait for bats as they exit their roots in the evening. Comparing the food components of bats by faecal analysis with the potential food availability measured in the foraging area, we suggest that the great evening bat is a selective predator. Bat guano, and the decomposing remains of dead bats that fall to the cave floor, feeds many small organisms that are then eaten by other forms of cave live. Bats are ecologically diverse, with a range of species that specialize in feeding on fruit, nectar, blood, fish, small mammals, and insects. The main hairs, when separated by blowing into the fur, are seen to be dark gray at the base, then broadly banded with yellowish brown, and tipped with dark brown; the three-colored hairs explain the name "tri-colored bat." … A colony of 300 Evening Bats was estimated to consume 6.3 million insects per summer, dining mainly on spotted cucumber beetles. The main predators for bats are birds of prey, such as hawks and owls, when they're flying and small mammals and snakes when they're roosting. Natural predators include owls, hawks, Raccoons (Procyon lotor), Black Rat Snakes (Elaphe obsoleta), and feral cats.
