The giant bumblebee (Bombus dahlbomii). A denizen of the southern Andes and widely believed to be in decline due to competition and perhaps spread of pathogens with two introduced European bumblebees that have invaded the region. You notice this bee when it flies by. Dramatically orange with yellow highlights on the traditional deep black integument of bumblebees.

A lovely slightly florescent orange bumble bee from Taiwan. So many combinations of color and form in each genus of bee!

Parasite. Nest parasite to be exact. Formerly in the genus Psithyrus these bees are now in the genus Bombus, with the rest of the bumble bees.

From the U.S. National Arboretum comes the now relatively uncommon Bombus fervidus. A species in delcine, but still present and how nice to have this one present right in Washington D.C. Pictures by Ashleigh Jacobs.

Ah, reaching way back in history now to 2012,,,,not completely satisfied with this shot of B. flavifrons, but it will have to do. From Wyoming, where a number of red butted bumble bees live.

Bombus fraternus. The Southern Plains Bumble Bee. This crisp, handsome and short-faced bee suffers from lack of an adequate publicist. Thought, several other Bumble Bees in its clan, to be in decline from introduced pathogens. It gets little mention in the bee press.

Bombus fraternus - Here is one of the very uncommon bumblebees that are of great concern these days, due to introduced parasites that have caused this species and its sister taxa to crash. Fortunately, they are still around, at least in small numbers.

This is one of the species that seems to be holding its own in terms of numbers. This worker has a corbicula on its tibia full of a mix of pollen and nectar

This is one of the species that seems to be holding its own in terms of numbers. This worker has a corbicula on its tibia full of a mix of pollen and nectar, it is laying on a piece of black felt. I like the the contrast in textures

Bumblebees are so charismatic. Here is a queen form downtown Washington D.C. very near the mall. Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200,
