damselflies Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies (which constitute the other odonatan suborder, Epiprocta) but are usually smaller and have slimmer bodies. Most species fold the win ...

Calopterygoidea Calopterygoidea is a superfamily of damselflies in the order Odonata. Families * Amanipodagrionidae Dijkstra & Ware, 2021 * Amphipterygidae Tillyard, 1917 * Argiolestidae Fraser, 1957 * Calopterygidae Selys, 1850 (broad-winged damselflies) * ...

. The family is small, consisting of around 78 species living species in nine genera occurring in the Palearctic, Australasia, and Asia. The family contains two subfamilies, Euphaeinae, encompassing all the living species and a single fossil genus, and the extinct Eodichromatinae, encompassing fossil genera from the Eocene to late Oligocene. Euphaeid species are large and mostly metallic-coloured, looking similar to species of damselflies in the family

Calopterygidae Calopterygidae is a Family (biology), family of damselfly, damselflies, in the suborder Zygoptera. They are commonly known as the broad-winged damselflies, demoiselles, or jewelwings. These rather large damselflies have wingspans of 50–80 ...

. The larvae have seven pairs of supplementary gills along the abdomen in addition to the usual three sac-like gills at the tip of the abdomen. Adults have the fore- and hindwings of equal length, barely petiolate and a long pterostigma that is broader in the hindwing. Adults have close veins and numerous antenodals (15-38), and most breed in forest streams.
