Family ANTHOPHORIDAE 



This is one of the very largest, if not the largest, family of bees in the world. It is present on 

 all the continents, although it is neither as abundant nor as well developed in the Australian and 

 Oriental regions as it is in the Holarctic, Ethiopian and Neotropical regions. The family is excep-
