A mating pair of Needham's Skimmer dragonflies spotted along the boardwalk that goes through the central wetland area at Huntley Meadows Park. The pair is shown "in wheel" in Photos 1-3 (of 4). All dragonflies and damselflies have a 10-segmented abdomen: male dragonfly secondary genitalia are located in segments two and three (2 and 3); female genitalia in segment eight (8). Therefore, the male dragonfly is on top; the female is on the bottom. The female half of the pair is shown in Photo 4, resting immediately after copulation with her male partner. Look closely at the full-size version of Photo 4. Notice the flanges beneath the female's eighth abdominal segment that are used to scoop and hold a few drops of water during oviposition.
