Detailed Description

A gynandromorph is a bee that exhibits characteristics of both sexes. In the other two species (Lasioglossum and Bombus) the split was bilateral..one side male and the other, female. In this Anthidium oblongatum (an introduced species) almost the entire bee is female with the apparent exception of having a seventh abdominal segment and genitalia. Note on the dorsal view the incomplete nature of the typical flange at the end of the segment. This specimen was collected by David Biddinger in his Penn State Apple Orchard Experiment Station Kingdom in South Central Pennsylvania. Picture was taken by Brooke Alexander. 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.
