Spotted Spreadwing

These imaged are of Spotted Spreadwings in our yard on 28 July and 3 August 2020. Spreadwings are damselflies that don’t completely fold their wings behind their backs. Spreadwings, at least for me, are exceptionally difficult to identify. They are told by the jagged brown stripe along their sides above their white undersides The bottom of the thorax has an often hard to see black spot. As they mature, males’ eyes turn blue and the abdomen develops a blue pruinosity. According to Dennis Paulson, an authority on damselflies and dragonflies, Spotteds are the most common spreadwings in western Washington. Nymphs tolerate a wide range of lake types, from ones that dry out in the summer to large ones full of predatory fish.
