Except for a few, most of the more than 1000 aphid species found in North America can’t be readily identified by sight or photograph alone. We show here a few of the color variations found so far. The dark ones in the first image can be seen in various states of development. In the second image a carpenter ant is tending to a gray variety of aphids. Aphids shed their skin periodically as they grow. The aphids in the third image were photographed on the floodplain on a mustard in mid – April 2012, the spring after the flood.
