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.
