Macrotera

Macrotera is a genus of bees native to North America, particularly diverse in the desert regions of the United States and Mexico.[1][2] According to Wilson and Carril, there are "around 30" species of Macrotera.[3] Macrotera are small to medium sized (2.0 mm to 16.0 mm) and often black or reddish in coloration. The genus was treated by P.H. Timberlake who, in addition to T.D.A. Cockerell, described most of the known species. Macrotera used to be considered part of the genus Perdita but was split apart by C.D. Michener in 2000. Most species are extreme specialists (oligoleges) with respect to pollen and will only collect pollen from a few closely related species or genera of plants, particularly the plant genus Sphaeralcea and various Cactaceae.
