 Agapostemon 

The genus Agapostemon is a common group of Western Hemisphere sweat bees, known as metallic green sweat bees because of their color. They are members of the family of bees known as Halictidae. Like other sweat bees, they are attracted to human sweat, and they use the salt from the sweat for nutrition.

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. They superficially resemble various members of another tribe, Augochlorini, which is also typically metallic green.

Nesting
All species of Agapostemon nest in the ground, sometimes in dense aggregations. Some species are communal such as A. virescens. In this and other communal species, multiple females share the same nest entrance, but beneath the common entrance burrow, construct their own portion of the nest. Thus each female digs her own brood cells and collects pollen and nectar to fashion the pollen ball upon which she will lay an egg.

Unlike other social bees, in communal bees there is no reproductive division of labor(can you explain this and/or link to an article about it?). The advantage of this form of sociality seems to be that cleptoparasitic Nomada bees have greater difficulty gaining access to the nest and brood cells when there are multiple females inside.This method of defense for the Cuckoo bee facilitates attacks for larvae of the Blister beetle.

Range
Some 42 species in the genus range from Canada to Argentina. In cool temperate regions, there is one generation per year, with females being active in the early summer and males and pre-diapausing females active in the late summer. Only mated females survive the winter (what is the death mechanism for unmated females?). Males can often be seen in large numbers flying around shrubs with large flowers, such as Rose of Sharon(This is from old wikipedia, I'd consider deleting since you don't have a citation for it and it's not yours... but up to you). Agapostemon angelicus are native to the Texas high plains. They specialized in being pollinators for cotton. They can serve as replacement for honey bees in pollination

Flight Patterns

Some species, such as the Agapostemon texanus, visit near flowers to save energy (What does this sentence mean?). Like other bees, A. texanus can fly from a short or long distance. Their flight patterns usually rely on flower density; they favor flowers with high densities. On long flights, A. texanus fly by close flowers. Their flight patterns best resemble the bumble bee and the honey bee. (This section doesn't totally make sense yet)
