Sweat bee, Agapostemon. The genus Agapostemon (literally "stamen loving") is a common group of Western Hemisphere sweat bees. They are members of the family of bees known as Halictidae. Unlike other sweat bees, they are not attracted to human sweat. They are generally green or blue, especially the head and thorax. Sometimes the abdomen in females is green or blue, although it may be striped, and most males have the yellow-striped abdomen on a black or metallic background. Unlike other social bees, in communal bees there is no reproductive division of labor. The advantage of this form of sociality seems to be that kleptoparasitic Nomada cuckoo bees have greater difficulty gaining access to the nest and brood cells when there are multiple females inside. They can serve as a replacement for honey bees in pollination.
