PHYLLOSTOMA next to Vampyrus contains the largest species in 

 the family, and the males possess a well developed glandular sac on 

 the throat opening in front of sternum. This is only rudimentary in 

 the females. These animals live in hollow trees or between large 

 leaves of plants, and resort to forest-clad districts. Like some of the 

 large insectivorous bats, the species of this genus may possibly feed 

 on smaller bats, which fact may have given them the reputation, 

 long borne by P. hastatum, of being sanguineous.
