Photo: Diane Edwardson, February 23, 2015. Sometimes you just capture the odd bee in a close up, but this one seems kind of mod. It has a rather large yellow & black geometrically shaped head, here, drinking from a non-native, invasive Wild Radish flower. (Click on photo to enlarge.)
Photo: Diane Edwardson, February 23, 2015. Even this view is greatly enlarged from a wider shot above the historic viaduct footings. I just happened to catch sight of the odd bee while editing photos. It only appeared in one frame.
UPDATE February 25, 2015: I'd submitted these photos to What's That Bug? The Bugman of Mt Washington posted his reply today. The mod little bug is not a bee, but a Flower Fly. (I knew it was a bizarre looking bee - it's legs weren't right either.) Read more on What's That Bug?
