Bats are small, flying mammals, most weighing less than one ounce. All Illinois bats eat insects. They are active in the warmer months and roost (rest) in trees, caves, under bridges, and in attics while raising their pups. As cool weather sets in, Illinois bats must either migrate to warmer areas or hibernate.
