Widow Skimmer (Libellula luctuosa) is a member of the Skimmer Family of dragonflies that is spotted during the summer and fall months at many water bodies in the mid-Atlantic United States, such as the wetlands at Huntley Meadows Park and ponds at Meadowood Recreation Area.
Widow Skimmers display sexual dimorphism. Although mature males and females look different, immature males and females look similar. Terminal appendages may be used to differentiate immature males from females.
Female dragonflies have a pair of cerci (superior appendages) that have little or no function.

Immature male Widow Skimmers and immature/adult female Widow Skimmers are nearly identical in appearance except for their terminal appendages.

Male dragonflies have three terminal appendages, collectively called “claspers,” that are used to grab and hold female dragonflies during mating: an upper pair of cerci (“superior appendages”) and a lower unpaired epiproct (“inferior appendage”).

Walter, could I email you one of my other images of this individual for your opinion? When enlarged, the photo appears to show something protruding from beneath the tip of the abdomen. That was what I thought could be an epiproct. It’s not visible in the image on my blog. Thanks for the ID assistance.

The dragonfly is definitely female. It appears some excrement is hanging from the tip of her abdomen. Hey, excrement happens! 😉 https://waltersanford.wordpress.com/2013/08/20/widow-skimmer-dragonfly-female/
