Tribe EUCERINI 



This is a very large tribe of pollen-collecting bees which is found on all the continents except 

 Australia. It is especially diverse in the New World, particularly in the Neotropical Region. In 

 America north of Mexico, the Eucerini are represented by 15 of the 18 genera known to occur on 

 the North American continent. Most of the species are solitary, but some live in colonies and all 

 make their nests in the ground.

The bees of this North American genus fly primarily during the spring months and are ob- 

 served only exceptionally during the summer. A second generation may occur in some species 

 since specimens have been collected as late as August. Insofar as known, the females do not col- 

 lect pollen from the flowers of Compositae, but visit the flowers of a wide range of plant fami- 

 lies, including especially the Ranunculaceae, Leguminosae, Hydrophyllaceae, Boraginaceae, and 

 Saxifragaceae. At least some of the species are apparently oligolectic
