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 (2). Some are parasitic, especially Sphecodes spp.(3)
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.
