Within the bird and insect kingdoms, species tend to be named on the basis of the appearance of the male and not of the female. This can be incredibly confusing, especially for a neophyte who is trying to identify an individual.
I remember be utterly baffled years ago when someone explained to me that the sparrow-looking bird in front of me was a female Red-winged Blackbird. What? How could that be? The “blackbird” was not black at all, and as for the “red wings,” there were none.
Over time I have become more familiar with the birds and the bees and some of the intricacies of sexual differentiation within species. I do not give too much thought that this pretty little female Eastern Amberwing dragonfly (Perithemis tenera) that I spotted last week at Green Spring Gardens has wings that are not completely amber-colored like those of her male counterpart.
Eastern Amberwings are the smallest dragonflies in our area at less than an inch (20-25 mm) in length. It is hard to miss the males as they buzz about low over the waters of ponds, but females tend to be much more elusive and often hunt far from the water. In the case of the one in the photo, she was perched on some vegetation in a bed of flowers a long way from the pond.
According to the Dragonflies of Northern Virginia website, “Amberwings are reported to have the most intricate courtship of any dragonfly. After the male selects several possible egg-laying sites for a mate, he flies off to find a female and leads her back to his potential nursery. To attract her, he sways back and forth, and hovers with his abdomen raised. Mating only occurs if the females approves—making this one of the few dragonflies where females choose the males.”
