Any of numerous predaceous insects of the suborder Zygoptera (order Odonata) having eyes that project to each side.
When at rest, the damselfly holds its narrow, membranous, net-veined wings vertically rather than horizontally, unlike dragonflies . Damselflies are more delicate and weak-flying than dragonflies but are similar in having male copulatory organs at the front part of the abdomen. They commonly fly in tandem during mating.
Male jewelwing damselfly ( Calopteryx splendens ).
