Food
For most species, primarily seeds. A few spp. prey on insects. Many members of the palaeotropical tribe Cleradini can feed on vertebrate blood. Clerada apicicornis is the only species known to also occur in the New World tropics (probably due to human transport); it consumes vertebrate blood, preys on insects, and is known to bite humans.
