Superfamily APOIDEA 1941 



timberlakei Cockerell. Calif. (Colorado Desert). Pollen: Oligolege of Mentzelia involucrata, but 

 also visits other flowers for nectar including Mohavea confertiflora, Phacelia crenulata, 

 P. distayis.

Subfamily NOMIINAE 



Members of this subfamily are especially numerous in the Old World tropics including those of 

 the Australian Region. They are relatively poorly represented in the Holarctic Region. Only the 

 widespread genus Nomia is present in the Nearctic Region and apparently all of the species are 

 polyleges, obtaining their pollen and nectar from the flowers of a wide variety of both native 

 and introduced plants. However, some of the species (e.g., Nomia nevadensis Cresson and N. tri- 

 angulifera Vachal) appear to collect pollen only from the flowers of the Compositae. At least one 

 of the species, the alkali bee (N. melanderi Cockerell), is an exceptionally valuable pollinator of 

 alfalfa (Medicago sativa) and has been managed successfully in artificial nesting sites so as to 

 enhance the pollination of this important agricultural crop.
