Bombus vosnesenskii, m, left side, Mariposa, CA
More black bumble bees from Yosemite National Park. Here is the male of Bombus vosnesenskii. This species was described by the relatively prolific Polish Taxonomist Oktawiusz Wincenty Bourmeister-Radoszkowski who pumped out a great many new descriptions of bees in many parts of the world. This was the era on both continents when military men did a lot of the natural history and our Polish friend was one of those, apparently entirely in the Russian army. He worked on taxonomy until his death (which is a given for taxonomists). Photography Information: 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 USGSBIML Photoshopping Technique: Note that we now have added using the burn tool at 50% opacity set to shadows to clean up the halos that bleed into the black background from "hot" color sections of the picture.
