Life Cycle
Typically ground-nesters, with nests formed in clay soil, sandy banks of streams, etc. Most species are polylectic (collecting pollen from a variety of unrelated plants).
Remarks
A few species are attracted to sweat, and will sometimes sting if disturbed, though the sting is not very painful (1).
Some species are parasitic, especially the genus Sphecodes (2)
See Also
Some metallic-green halictids superficially resemble cuckoo wasps (Chrysididae), but halictids lack the sculptured cuticle and the ability to curl up in a protective ball.
