Evening bats have short, black, narrow wings and blunt rounded ears. They often roost in colonies in houses and other buildings, and because of this are sometimes considered a nuisance. Females typically form maternity colonies of 30 to several hundred individuals.
Evening bats leave their roost shortly after sunset and feed over fields, ponds and along watercourses. They eat beetles, moths and caddis flies.
