Autumn Meadowhawk dragonfly terminal appendages

Autumn Meadowhawk (Sympetrum vicinum) is a member of the Skimmer Family of dragonflies that is commonly spotted during the fall months at many water bodies in the mid-Atlantic United States.

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”).
