Family ANDRENIDAE 



This is a large family of pollen-collecting bees which is present on all the continents except 

 Australia. Nearly all of the species excavate their nests in the ground and most are solitary 

 although a few species in each of the two subfamilies live in colonies. Their intrafloral relation- 

 ships are varied and range from numerous examples of oligolecty in varying degrees to broad 

 patterns of polylecty. 



Even though both subfamilies are well represented in America north of Mexico by a great 

 many species, the majority of our fauna consists of the chiefly Holarctic genus Andrena and the 

 Nearctic genus Perdita.

Genus ANDRENA Fabricius 



Since studies of the relationships of the numerous subgenera within the genus Andrena are 

 incomplete, the subgenera are arranged alphabetically in this catalog. Those species currently 

 not assigned to any subgenus are placed after the recognized subgenera.
