[email protected] Damselfl ies Zygoptera Broad- winged Damsel Family Calopterygidae Large, showy damselfl ies of this family often display metallic bodies and/or colored wings. They are distinguished from other North American damselfl ies by broad wings with dense venation and no hint of the narrow petiole or “stalk” at the base that characterizes the other families. The nodus lies well out on the wing with numerous crossveins basal to it. Colored wings in this family are heavily involved in displays between males and of males to females. This is the only damselfl y family in which individuals point abdomen toward the sun (obelisk- ing) at high temperatures. Closed wings are held either on one side of the abdomen or above it, which may relate to temperature regulation. Leg spines are very long, appropriate to fl y- catching habits. Worldwide it is tropical, with a few species in temperate North America and Eurasia. World 176, NA 8, West 6. Jewelwings Calopteryx These are the most spectacular damselfl ies of temperate North America and Eurasia, all large with metallic green to blue- green bodies.
