Insectivorous bats consume a vast quantity of bugs every night. A single brown bat can catch over 1000 mosquito-sized insects in an hour. But not all of them eat insects. Many bats, particularly in temperate weather zones, eat fruit. The seeds are then dispersed over a wide territory through the bat droppings, thereby spreading the growth of a particular species of plant.
Some bats feed on pollen and nectar.
There are many plants that have evolved so that they can be pollinated by bats. The problem More than half of the species of bats in the United States are endangered or in rapid decline. Although they have natural enemies such as foxes, snakes and possums, it's humans that pose the greatest threat. When people develop land that was once inhabited by bats, they destroy roosting sites. When bats seek alternative living areas, they sometimes pick small openings in buildings and get inside attics.
