Monster cleptoparasite, this dramatic species is a nest parasite of bees in the genus Centris and is endemic to South America. Note the one shot of the lovely expanded tibial spurs. I do not know their function, but it may have to do with nest invasions, either digging or gripping the walls of the nest. Lovely metallic blue / purple colors.

The red maple, Acer rubrum, often one of the most dominant trees in deciduous woods in the East. It blooms very early in the spring and provides pollen and nectar to the set of bees, and flower flies, that come out early.

Ohio Buckeye. Aesculus glabra. Nice open understory tree you see more towards the west in Maryland and the Eastern U.S. Attracts a variety of woodland loving bees...in particular Augochlora pura. A nice color match. Picture and specimen by Helen Lowe Metzman.

Amegilla....one of a large group of large Old World bees that blend and fracture colors in wonderful ways. In this case this male Amegilla from Australia from the Laurence Packer Lab bee slots in a whole series of subtly iridescent green hairs amidst a mix of white and black, quite nice and surely a useful design for a rug or tapestry of some sort.

From Kruger National Park: Amegilla atrocincta. Amegillas come in a variety of sizes and shapes, but most are larger than honey bees. Most too are laddered with bold white stripes across the abdomen (A.

A large bright green with blue overtones Agapostemon from Badlands National Park. One of several species present there and very similar to A. virescens and a bit tricky to tell apart. Photo by Wayne Boo with help from Ben Smith on upping the Photoshopping techniques.

Male Agapostemon's almost all have this same pattern, Metallicy green on the head and thorax and then striped yellow and black on the abdomen. Females uniformly don't have yellow anywhere. Why is good question as this male yellowness syndrome runs throughout the bee kingdom, cutting across families.

Another bee associated with deep sandy soils. This one also found in a study sand pit reclamation in Anne Arundel County in Maryland. Amazing to think that such metallic green bees are all around us having done their business for millions of years.

Anthidiellum - Latin dimunitive of the the larger, and more robust, genus Anthidium. This little bees often go unnoticed both because they are very small and because they are very fast...zipping from flower to flower seemingly without resting.

A lovely little southern pea loving bee. Its so nice to know that these little flying jewels are out there and not everything is a honey bee. Collected by Sabrie Breland in the southern pinelands of Georgia and photographed by Sara Guerrieri.
