Evening bats that roost together seem to share information about the location of rich foraging patches and alternative roosting sites. When they forage on farms, they are a boon to farmers, because the bats eat cucumber beetles (the adult stage in the life of the southern corn rootworm). Evening bats have never been found roosting in caves. Summer maternity colonies have been found in buildings and hollow trees; in the winter, bats of this species have been found roosting in palm fronds in Florida. Females and young appear to migrate fairly long distances; one individual was located 520 km from where it had been caught and tagged. Only females migrate northward in the summer; males apparently remain in warm southern locations year-round.
