Halictidae
Halictidae is the second-largest family of bees (clade Anthophila) with nearly 4,500 species. Halictid species are an extremely diverse group that can vary greatly in appearance. These bees occur all over the world and are found on every continent except Antarctica. Usually dark-colored (frequently brown or black) and often metallic, halictids are found in various sizes, colors and patterns. Several species are all or partly green and a few are red, purple, or blue. 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 one of many with short tongues and is best distinguished by the arcuate (strongly curved) basal vein found on the wing. Females in this family tend to be larger than the males. They are commonly referred to as "sweat bees" (especially the smaller species), as they are often attracted to perspiration. Ecology Most halictids nest in the ground, often in ha ...
