context_page_description: Halictidae is the second-largest family of Anthophila bees. Halictid species occur all over the world and are usually dark-colored and often metallic in appearance. Several species are all or partly green and a few are red; a number of them have yellow markings, especially the males, which commonly have yellow faces, a pattern widespread among the various families of bees. The family is distinguished by the arcuate basal vein found on the wing.
  They are commonly referred to as "sweat bees", as they are often attracted to perspiration. They are only likely to sting if disturbed; the sting is minor.
