RECOGNITION
Recognition
BugGuide.net: "Forewing and hindwing similar size and shape, held at rest above body (except Spreadwings.) Very slender abdomen. Male has four terminal appendages and female has well-developed ovipositors. Broadwinged damsels (Jewelwings, Rubyspots) have wider wings than Pond Damsels and may have colored or spotted wings (most Pond Damsels have clear wings except for pterostigma.). Spreadwings are readily identified because they do not fold the wings together snugly--they also typically "hang" from a perch, with wings slightly spread. Males and females are typically different in color, with the male showing more brilliant color, though some female damsels are also brightly colored. In some species females have both a male-form and a female-form color pattern. Identification is made by noting details of markings on head, thorax, and abdomen."
