Before and After

On Saturday, 25 January 2014, I had the honor of co-presenting a program called “Flying Dragons” with Kevin Munroe, former Park Manager, Huntley Meadows Park. Kevin invited me to talk about how to make the transition from a beginner- to intermediate/advanced-intermediate dragonfly hunter. I prepared a photoblog post related to my part of the program, called “Five steps to the next level of dragonfly spotting.” Step 1 is as follows.

Step 1. Be aware the same species of dragonfly may appear differently depending upon gender, age, and natural variation. Some species display sexual dimorphism; in contrast, both genders look virtually identical for some species. Finally, females of some species display polymorphism (also known as polychromatism).

Male Needham’s Skimmer dragonflies (Libellula needhami) look different depending upon age, as shown by the “Before” and “After” photos (below). Further, immature male Needham’s Skimmers look similar to immature/mature females of the same species. Although this might be confusing for a beginner dragonfly hunter, with patience and persistence everything falls into place relatively quickly.


Male Needham’s Skimmers were photographed during photowalks at Painted Turtle Pond, Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA in late-June and again in late-July. Notice the dramatic difference in appearance of the same species of dragonfly.

    I think that many of us would like to rely primarily on color in identifying dragonflies. Your post wonderfully illustrates the dangers associated with that approach, Walter, and the need to look more closely at other identifying features. Patience and persistence helps, but it seems like there is always more to learn, which is both a blessing and a curse.
