Beekeepers describe their honey bees as "my girls" or "my beautiful girls."
It's a term of endearment.
Now take the green metallic sweat bee, Agapostemon texanus. If honey bees are beautiful (and they are) then these bees are spectacular.
Sometimes called ultra green sweat bees, the females are metallic green from head to thorax to abdomen. The males, however, are metallic green from head to thorax. Their abdomens are striped.
This is one of the bees that native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis, studies. When he monitors the Häagen-Dazs Honey Bee Haven, the half-acre bee friendly garden next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis, he finds these periodically.
The Agapostemon are members of the Halictinae family, described in the book, Bees of the World, by Christopher O'Toole and Christopher Raw, as a world-wide group of bees. They are "often called sweat bees because in hot weather they are attracted to human perspiration, which they lap up, probably for the salt it contains," they write.
Some of the family's many genera, including Agapostemon, are restricted to the New World. Halictus and Lasioglossum "are common to the Old and New Worlds," according to O'Toole and Raw.

How blue can it be?
We spotted a metallic blue bug, one of nature's most amazing colors, last Sunday.
It was in the Mostly Natives Nursery in Tomales, a Marin County site frequented by many University of California entomologists and staff as they work on their urban bee research and publications. They come by to check out the native plants and the insects.
This blue bug was crawling up and down a Euphorbia (genus Euphorbia, family Euphorbiaceae), an unusual plant in itself because it appears to have green blossoms.
What was this bug?
We asked Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at the UC Davis. Kimsey surrounds herself with more than seven million insect specimens, and I swear she can recite the genus and species of everyone of them.
(At least we all think so!)
So, what was this bug?
She and senior museum scientist Steve Heydon initially identified it as a juvenile harlequin bug, family Pentatomidae. Kimsey later said--and confirmed--that it's a bordered plant bug, family Largidae.
