(Cockerell, 1906)

This bee nests in salt-saturated, or alkaline, soil. Alkali bees are an effective pollinator of alfalfa.[2] The bee uses a specialized technique of opening alfalfa flowers for pollination by applying pressure to snap open the keel of the flower. Due to the unusual nesting habits of this bee, farmers have developed methods to accommodate them.[3]

It is preyed upon by the conopid fly Zodion obliquefasciatum.[4]
