Bombus citrinus, Male, Face, Cecil County,MD

The odd case of Bombus citrinus. This species is a nest parasite on other Bumble Bees and as is the case in many, if perhaps not all, the parasitic species it has an unusually long top of the head...in other words the distance from the ocelli to the back of the head is longer than in other species. Collected by Tim McMahon in Cecil county and photographed by Colby Francouer. 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.
