throughout NA and worldwide
Almost all species feed principally on seeds. Only a few species may be predatory on other insects. One tribe mostly only in the Old World tropics, Cleradini, has many members that can and do actually feed on vertebrate blood. Clerada apicicornis is the only species known to also occur in the New World tropics, however, probably due to human transport. It consumes vertebrate blood, predates on other insects, and is known to bite humans.
