Rare Parasitic Bee (Nomada obliterata). Some bees are just rare. Or, at least rarely found. This specimen here is the first known specimen from Washington D.C. where it was discovered at Kenilworth Aquatic Gardens, along the long neglected Anacostia River. Neglected but not absent of biodiversity. What is the "obliterata" part of its name about? It has to do with the fact that it normally 3 submarginal cells in the wing have been partially obliterated and but 2 remain. Chelcey Nordstrom captured the specimen and did the photography.
