In my experience, female Needham’s Skimmer dragonflies (Libellula needhami) seem to be more abundant than males toward the end of the adult flight period for that species.
Two Needham’s Skimmers were photographed during photowalks at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA. Both individuals are mature female, as indicated by their terminal appendages and muted coloration.

Post Update: Sincere thanks to Drew Chaney for identifying the flowering plant shown in the preceding photo. According to Drew, “It’s either Clematis terniflora or virginiana. I can’t tell without leaves: Terniflora has entire leaves; virginiana has toothed ones.”
