Identification guides for birds, dragonflies, and damselflies often use illustrations rather than photos? Why? It is almost impossible for a photo to show all of the key identification features of a species.
Last week, for example, I captured some wonderful photos of a male Aurora Damsel damselfly (Chromagrion conditum) at a small pond in Prince William County, Virginia. In the first photo below, I was able to capture an image from almost directly overhead that shows the markings on the tiny damselfly’s thorax and abdomen. The image also shows how this damselfly species perches with its wings partially spread, unlike most damselflies that perch with their wings closed above their bodies. The second shot shows many of the same features.
However, it is fairly uncommon to be able to capture views like those in the first two shots and they do not show what is often the key identification feature for this species. Both genders of Aurora Damsels have distinctive bright yellow patches on the sides of their thoraxes, as you can see in the third photo. You might notice that in this photo, the markings on the tip of the abdomen are much less clear than in the first two shots, but that’s not a problem, because that yellow patch immediately signals that it is an Aurora Damsel.
Whenever I can, I try to capture shots of my subjects from multiple angles. The different angles of view may help in identifying a species or may create a more aesthetically pleasing image. One of the coolest things about photography is the way in which it combines science and art—I can be as scientifically geeky or as artistically creative as I want to be.
